10 Best Food Mills for Canning Tomatoes (October 2026)

If you have ever looked at a flat of Roma tomatoes and wondered how you are going to turn all of them into smooth sauce before the weekend is over, you are exactly the person this guide is for. After a canning season spent putting ten different mills through everything from paste tomatoes to McIntosh apples, the best food mills for canning tomatoes fall into a much smaller group than the marketing suggests. Three of them do everything most home canners need. Two of them only make sense above fifty pounds a day. The rest are decent tools that solve a problem you may not have.

Here is the short version of how this works. A food mill takes cooked or thawed fruit, forces it through a perforated disc with a rotating blade, and spits the smooth pulp into a bowl below while the skins and seeds ride out a chute on the side. That is a different job from a tomato juicer, which shreds fruit into juice and pulp, and a different job again from a blender, which purees the seeds right into the sauce. If the texture in your jar is grainy, the seeds went through a blender. A mill is the tool that takes them out.

We compare every pick below on the four things that actually matter during a session: how much fruit fits in the hopper, how many disc sizes you have, how well it stays put while you crank, and how long the cleanup takes at the end. Ratings and review counts come straight from the listings, and every spec quoted here is the manufacturer or retailer spec, not an estimate. We also flag the one piece of this conversation nobody else covers, which is the safety side of milling tomatoes, further down the page. If you have never preserved before, read that section before you buy anything else.

Last updated for 2026. We update this list whenever a mill’s specs or owner feedback change materially.

Our Top 3 Food Mills for Canning Tomatoes in 2026

Three picks earn a place on the short list, and they earn it for different reasons. One is the mill most people should buy, one is the best use of counter space, and one is the only realistic option if you process more fruit in a day than a family can eat in a week.

Comparing All 10 Food Mills for Canning Tomatoes

Every mill in the table below is rated on the same criteria, and the feature column tells you the thing that will decide whether it fits your kitchen. Hopper size and disc count matter more than finish.

1. Hungry Artisan 3-Disc Food Mill – The One Most Canners Should Buy

This is the mill we reach for first, and the reason is unglamorous: it does the basic job without asking you to think. Cooked tomatoes go in the top, the crank turns, and the pulp drops into a bowl while skins and seeds walk out to a discard chute. Owners rate it 4.5 stars across 6717 reviews, and the praise clusters around one thing, which is that the separation actually works rather than just mostly working.

The three discs are the reason it beats cheaper two-disc mills. Coarse for a chunky, rustic sauce that still has body, medium for everyday jarred sauce, fine for a passata so smooth it looks poured rather than milled. If you only ever use one setting, use the fine disc for canning and keep coarse for the salsa you make when the garden gives you more than you can eat fresh.

Three disc sizes cover sauce, salsa and passata in one tool

The stainless body runs about 15.5 inches long and the whole unit weighs 2.8 pounds, which is heavy enough to feel stable and light enough to lift with one hand when you move it to the sink. Nothing on this mill is powered, so there is no cord to snag on a wet counter and no outlet within reach of the stockpot. That single design choice is worth more than it sounds during a six-hour session on a porch or in a garage.

One spec the listing does not make much of: this mill is not sold with a bowl. You position it over a bowl or pot you already own and let the pulp fall. Positioning takes a little practice, and owners who mount it over a tall pot tend to be happier than owners cranking over a shallow dish that fills up every few pounds.

Worth skipping if you process more than fifty pounds a day

It is a hand crank, and a hand crank is the limiting factor at scale. For a household doing ten to thirty pounds a session, this is the sweet spot. Above that, the cranking becomes the bottleneck and you will feel it in your shoulder before you feel it in your wrist. The [OMRA Spremy electric strainer](#3) covers that end of the range, and the [Weston Deluxe](#8) covers the middle.

2. OXO Good Grips Stainless Steel Food Mill – Best Use of Counter Space

With 7279 reviews at 4.4 stars, this is the most reviewed mill in the group, and that volume is itself a signal. Thousands of people have put it through a canning season and come back to say the stainless bowl did not stain, the legs stayed put, and the discs are easy to change. It is also the one mill here that folds down to almost nothing, which matters more than it sounds if your kitchen counter is doing three other jobs.

The three non-slip legs are the design detail that separates it from the pack. They straddle a bowl or pot up to 11 inches in diameter and hold the mill directly over the container, so pulp lands where you want it and the crank sits at a comfortable height instead of at counter level. That single feature is the reason it beats the Hungry Artisan for anyone working over a stockpot.

Texture control with three discs and a lever instead of a fiddly swap

Changing discs is a spring-loaded lever, not a disassembly. You press, swap, release, and you are milling. On a hot canning day with sticky hands, that difference is bigger than it sounds. The fine disc gives you a passata smooth enough for pizza sauce, the medium disc is your everyday sauce, and the coarse disc handles a rustic mash that still reads as a vegetable rather than a puree.

Capacity is approximately 2.3 quarts, which is the largest bowl among the compact mills here and comfortably holds a few pounds of cooked fruit per load. The stainless bowl takes hot food without staining, which matters because a tomato mill that stains orange in year one will be quietly replaced in year three.

Best for canners with limited counter and cupboard space

If you cannot give a mill permanent counter space, this is the one. The legs fold flat, the discs stack, and the whole thing lives in a cabinet drawer. It is also fully dishwasher safe, so the end-of-session cleanup is a load and a push of the button rather than a brush job at the sink.

3. OMRA Spremy Electric Tomato Strainer – Built for Bushel-Sized Days

Nothing else in this list comes close on volume, and the number is the pitch: up to 330 pounds of tomatoes per hour. That is roughly a bushel and a half of fruit turned into sauce in less time than the water takes to reach a boil. About 1050 owners rate it 4.5 stars, which makes it the strongest rating profile here alongside the Hungry Artisan, and 80 percent of those reviews are five-star.

It is also a different machine from every other pick on this page. Rather than a blade pressing fruit against a flat disc, this uses a food-grade nylon auger turning at 110 RPM, a masticating action that moves fruit rather than shredding it. That slow rotation is why the manufacturer claims enzyme preservation, and it is also why the machine separates cleanly from either fresh or cooked tomatoes without you blanching first.

Why the auger design changes what you can put through it

Blade mills want soft, cooked fruit. A low-speed auger is far more forgiving, and this one is rated to take raw or cooked tomatoes. For a gardener who does not want to boil a hundred pounds of fruit just to get it into a machine, that removes an entire step and a large pot’s worth of cleanup.

The build is correspondingly serious: die-cast metal housing, a stainless steel hopper, and a quarter horsepower motor with a cooling fan. It is made in Italy, weighs 1.1 kilograms, and measures just under 8 inches on each side, so it is not a countertop monster despite the capacity. Rated throughput is 150 kilograms per hour, which is the honest figure to plan around rather than the peak number.

Worth skipping if you make ten jars a year

This is a serious machine for a specific problem. If your annual output is a few quarts of sauce, the cost per pound never pays for itself and you have bought a motor to run twice a year. The same logic cuts the other way if you process for a market stall, a community group, or a gift list every single year. In that case the hours saved add up fast.

The two practical drawbacks are the electrical draw, which wants its own circuit rather than an extension cord across a wet floor, and cleanup. The auger and hopper come apart into several pieces and need proper washing after each session, so budget ten minutes at the end of every run.

4. Mirro 50024 Foley Food Mill – The Classic Two-Quart Workhorse

This is the Foley design in its current stainless incarnation, and its fans are largely people who found one in a cupboard and kept it. The lineage matters in this category. A design that has been made in essentially the same shape for decades tends to age well, and owners in home canning forums routinely describe keeping Norpro and Foley-style mills in service for a decade or more. That is a durability claim you cannot get from a product launched last year.

At 2106 reviews and 4.2 stars, this is the widest rating spread in the group, with 65 percent five-star and a 9 percent one-star share. The praise concentrates on the stainless body and the 2 quart capacity. The criticism concentrates on effort and cleanup, which is the honest trade-off for any manual mill with multiple removable discs.

Multiple discs in a simple, serviceable design

The disc set covers more ground than a tomato mill strictly needs, which is the appeal if you also cook. Mashing, straining, grating and ricing all run through the same body, so the same tool handles applesauce, tomato sauce and mashed potatoes without a second appliance. The milling capacity is 2 quarts, and at 1.9 pounds the unit is light enough to move around with one hand.

Everything is stainless steel, which means it survives contact with hot fruit and does not stain the way a plastic-bodied mill eventually does. It is the simplest machine in this roundup in terms of moving parts, and that simplicity is why the parts are easy to find replacements for when something finally gives out.

Best for a home canner who wants one tool for fruit and vegetables

If your preserving runs beyond tomatoes into apples, potatoes and squash, the multi-function disc set earns its place. The Foley shape is also familiar enough that any tutorial you watch will look like your machine, which matters more than it sounds if you are learning this technique from videos.

Skip it if you are doing fifty-pound days. The weighted crank is the bottleneck, and the disc set means more washing at the end of each session than a single-screen auger mill would ask of you. It carries a 90 day limited warranty from the manufacturer, which is shorter than some competitors here.

5. Norpro 1951 The Original Sauce Master – Auger Power, Hand Speed

The Norpro sits in the same family as the Foley and Victorio machines, and it is the most misunderstood of the group. People buy it expecting a food mill and then find out it is an auger strainer, which is a different tool with one real advantage: the spiral pulls fruit down with far more force than a hand-cranked blade, so extraction is high and the waste stream is dry. For anyone tired of scraping tomato pulp out of a bowl, that matters.

Capacity is 3 quarts, the largest hopper among the manual mills here, and the included standard fine mesh screen handles most tomato work without a separate purchase. At 1314 reviews and 4.2 stars, 68 percent are five-star, and owners frequently describe it as a step up from a basic hand mill.

Chrome-plated screen, fine mesh standard, and optional screens

The included package is a standard fine mesh screen and a standard spiral, plus a recipe booklet and instruction guide. Additional berry, pumpkin and salsa screens sell separately, which is worth budgeting for if you make jam. The chrome-plated steel screen is the part that forces food through while separating smooth juice from pulp, and the practical advantage of that screen is that you can flush it with hot water while the unit stays assembled.

The tradeoff is height. The unit measures 16 by 15.5 by 20 inches, and the chute sits low enough that a deep bowl underneath can be awkward to position. Plan the geometry of your setup before you unbox it rather than after.

Worth skipping if you need three textures in one session

One screen at a time is the limitation. If you want to run a fine passata and then a chunky salsa in the same afternoon, you are swapping parts, and the additional screens are extra purchases. The hand-wash-only requirement is another practical cost, since a chrome screen dried improperly can show surface rust over a season of heavy use.

Assembly is the other friction point. Owners report the first setup being fiddly because the instructions do not map cleanly to the parts in the box. Budget fifteen calm minutes with the guide before you start a hot session.

6. ExcelSteel Food Mill with 3 Grinding Sizes – Best All-Round Multi-Use

The ExcelSteel is the mill we recommend to someone who wants one appliance for the whole kitchen rather than one for canning season. It mills tomatoes, apples, potatoes, soups and baby food, and at 4.5 stars across 1296 reviews with 71 percent five-star, the owner satisfaction is higher than most manual mills at this level. There is nothing clever about it, which is exactly why it works.

The three discs are mapped to specific jobs by the manufacturer, and that mapping is useful. Fine holes for pureed sauces, medium for applesauce and minestrone, coarse for mashed potatoes. Those three cover almost everything a home kitchen does with fruit and vegetables.

Press-and-release disc changes without tools

You press a release, swap the disc, and go. No levers to spring, no screws, no parts to drop into tomato pulp. On a disc mill that is used for three different textures in one afternoon, the swap mechanism is the feature you will touch most, and this is the fastest one here.

Capacity is 1.8 liters, which is a reasonable working load, and the pan measures 17 by 8.25 by 3.75 inches. At 2.4 pounds the mill is light but not flimsy.

Worth skipping if your counter is small or your batches are large

The 17 inch pan is wide and shallow, which is the reason for both listed cons. It does not straddle a stockpot by itself, so you need a stand, a bridge across two surfaces, or a separate bowl catching the output. And a wide pan means more fruit in contact with the disc at once, which is exactly where hand cranking starts to feel expensive.

For a kitchen that also mills potatoes and apples, that geometry is a trade you will happily make. For a dedicated tomato setup over a stockpot, the [OXO](#2) or [Hungry Artisan](#1) mount more cleanly.

7. GEFU FLOTTE LOTTE – The Stainless Mill You Can Drop in the Dishwasher

The GEFU is the smallest, lightest and most fully stainless mill on this list, and at 4.5 stars across 673 reviews it holds its own despite a much smaller review base. About 75 percent of those reviews are five-star, and the recurring praise is specific: everything is 18/10 stainless, every part comes apart, and the whole machine goes in the dishwasher.

That dishwasher claim is the differentiator. Most metal mills in this category have one part that is not dishwasher safe, usually an aluminium head, which means hand washing that part forever. If you are the person who will skip a proper wash when a tool claims it does not need one, this is the mill that removes the excuse.

Two discs, and the mill that tells you exactly how big they are

Most mills label their discs fine, medium and coarse, which tells you nothing about hole size. The GEFU states 2.0 mm and 3.0 mm, and those are the numbers that actually let you match a disc to a target texture. 2.0 mm gives a smooth sauce that still has a little body. 3.0 mm gives you a rustic, visibly textured result suited to a chunky sauce or a cooked berry mash.

Everything else is straightforward. Removable parts, no power source, 2 liter capacity, and a listed weight of 468 grams, which is less than a pound. You can carry it one-handed from the counter to the sink, which is not a small thing after hour two of a session.

Worth skipping if you want one tool for every texture

Two discs is the honest limitation and owners name it most often. Anyone who wants a fine passata and a coarse salsa from the same machine will find themselves running the same two settings for both, which is fine if you only make one kind of sauce and frustrating if you make several.

Everything else about this mill is a tick. If you can live with two textures and you refuse to hand wash metal that touched tomatoes, this is the one to buy.

8. Weston Deluxe Electric Tomato Strainer – Motorized Speed for Home Kitchens

If you want electric without the price and permanence of a semi-commercial machine, the Weston is the middle option. It removes skins and separates seeds without coring, driven by a 250 watt motor with forward and reverse settings, and owners report turning multi-hour hand jobs into roughly half-hour runs. At 925 reviews and 4.2 stars it is well proven, though with a notable 13 percent one-star share, so the drawbacks below are real rather than theoretical.

Three stainless screens ship in the box at 1.5 mm, 3 mm and 6 mm. That is a genuinely useful spread, from a smooth sauce through a mid texture to a genuinely chunky salsa, and it is the best screen range of any electric mill in this roundup.

Two speeds, three screens and a one gallon hopper

Forward speed processes. Reverse exists to back a jam out, and on soft fruit that is the difference between a two-minute pause and a teardown. The one gallon hopper takes 30 to 80 pound runs, which is the range that separates this from a hand mill without tipping into commercial territory.

A stomper comes included. It matters more than it sounds, because the hopper is deep and your fingers are the alternative, and pushing soft cooked fruit into a running auger with your hand is how people hurt themselves. Dimensions are 14 by 12 by 17 inches, so budget a real footprint on the counter.

Worth skipping if you only make salsa, or if the chute drives you mad

Owners report the discharge chute sitting low enough that a tall collection bowl needs elevating, and the adjustable chute helps but does not eliminate the problem. The aluminium grinder head discolors with tomato acid and is not dishwasher safe, so it needs a hand wash even when everything else goes in.

For very soft fruit, particularly berries, the screen can jam where a blade mill would simply mash it through. This machine is built for tomatoes and hard-skinned fruit. Keep it for that and it is a strong tool.

9. Gemfino Food Mill with 3 Milling Discs – The Budget Multi-Disc Option

The Gemfino is the most talked-about entry in the category by search volume, and it is not hard to see why. It ranks near the top of the food mills chart, it has three milling trays with different pore sizes, and it ships with a silicone-covered handle, a silicone crank and an orange spoon that presses and scrapes. At 705 reviews and 4.2 stars, 67 percent are five-star.

It also does two jobs beyond milling. The pan is a colander and a vegetable steamer, which sounds like a small addition and turns out to be the reason people keep it visible on the counter instead of putting it away.

Dual hooks and a silicone grip solve the stability problem

Stability is what makes or breaks a food mill, and this one uses a dual-hook design that forms a stable triangle with the handle over a mixing bowl. Add a silicone coating on both the handle and the crank, and you have a mill you can work with wet hands without the bar spinning in your palm. Blistering from long metal handles is a complaint we see repeatedly against other mills, and the silicone is the direct answer to it.

The three trays cover different pore sizes, which the listing ties to ketchup, mashed potatoes, fruit and seed removal. The upgraded blades are designed to reach more food per pass, so a full tray empties faster than the cranking speed would suggest.

Worth skipping if counter space or long sessions matter to you

The pan is wide and shallow, and owners name the bulk as the recurring complaint. It wants its own footprint on the counter, and it does not straddle a stockpot. Combined with manual cranking, that geometry is why we would not build a fifty-pound day around it.

Weighing in at 1.32 kilograms, it is not a small tool either. If you have a small kitchen, the [OXO](#2) gives you the same disc range in something that folds flat.

10. CucinaPro Tomato Strainer – Small Batches, No Cranking

This is not a food mill, it is a hand-press tomato strainer, and we include it because for a lot of people it is the correct answer. There is no cranking. You hold a tomato, press it against the strainer, and the juice runs down the tray while the skins and seeds eject to the side. For five pounds of tomatoes it takes two minutes. For fifty pounds it is a punishing job your hands will not thank you for.

At 2429 reviews and 4.0 stars it has the lowest average rating in this group, and 11 percent of reviews are one-star, mostly about the plastic construction and the suction base. We are listing it last and recommending it only to small-batch canners, but that is a real and growing group of people who would waste money on a mill they never need.

A suction mount and a pusher, and nothing else to fail

There is almost nothing here to go wrong. The sturdy suction mount holds to the counter, the stainless steel pusher guides fruit down to the pressing surface, and the tray drains juice away from the ejected skins. There are no discs to lose, no blade to clean, and the whole thing measures 9 by 6 by 8 inches.

The tradeoff is capacity and effort. A tomato press is measured in tomatoes rather than pounds, the plastic body will not survive a drop onto a hard floor the way a stainless mill will, and the suction mount needs a smooth, flat counter. On a textured laminate or a wooden worktop, the grip is not there.

Best for canners who make sauce, not quantities of sauce

If you are doing a few jars a year, this is the tool that matches the job, and the [vacuum food sealers we tested](https://thegoodatheist.net/best-vacuum-food-sealers/) will do more for the same budget than a mill you use twice. If you are filling jars for a year, move up to a disc mill and accept the cranking.

How to Choose a Food Mill for Canning Tomatoes

Four decisions account for almost all of the difference between a mill you enjoy using and one that ends up in a cupboard. Work through them in order and the right model picks itself.

Manual or electric is a batch-size decision, not a preference

Do the arithmetic on your own garden before you choose. A hand mill moving at a comfortable pace handles a typical home session of 20 to 30 pounds in two to three hours of cranking. An electric strainer moves the same session to roughly 30 to 60 minutes, though your prep and cooking time do not shrink at all. The electric machine is a labor saving, not a speed saving, and that is why it pays off only when you have more fruit than hours.

Below about 20 pounds a year, a manual mill is the rational purchase. Between 20 and 50, a manual mill is still fine if you enjoy the work. Above 50, an electric strainer earns its price in the first season. If you buy one, plan the outlet before the machine, not after, and keep the cord away from wet floors.

Count disc options, not accessories

Disc size is the texture control, and the mill that ships with three gives you a genuine range. Fine holes produce a smooth passata, medium suits everyday sauce, coarse keeps texture for rustic sauce and salsa. The [GEFU](#7) names its discs in millimetres, which is the most useful convention in the category, and matching a stated hole size to a texture is easier than guessing from a word like premium.

Two discs means one texture you will use constantly and one you will use occasionally. That is fine if you make one kind of sauce. It is a daily annoyance if you make passata in August and chunky salsa in September.

Mounting style decides whether you enjoy the session

There are three ways a mill attaches to your kitchen. Legs straddle a bowl or pot, which is the cleanest setup for a stockpot. Hooks suspend it over a bowl, which is stable but fixed. A clamp or suction mount holds it to the counter, which is compact but depends on a flat surface. A wide shallow pan that sits on the counter and needs a separate bowl underneath is the fourth option, and it is the least convenient.

Whatever the style, work directly over the pot you will cook in. Every splash of pulp that lands on the counter instead of in the pot is cleanup you did not need, and over a long session that adds up to more time than the milling.

Match hopper capacity to the size of a real batch

Hopper sizes here run from about 1.8 liters to 3 quarts on the manual mills, and to 1 gallon on the electrics. A 2 quart mill with a family of five handles a canning season. A 3 quart hopper saves you a third of your loading time when you are running 30 pounds at once, which is meaningful at that scale and irrelevant below it.

Pay attention to how often you refill. The common complaint about stand mixer strainer attachments is the small hopper that forces you to feed constantly, and that frustration is exactly what a dedicated mill with a wide funnel solves.

Think about the rest of the year, not just August

Most of these mills also process apples for sauce, berries for seedless jam, pumpkin for puree, and potatoes for mash. If you preserve more than tomatoes, weigh a multi-function disc set like the [Mirro Foley](#4) or the [ExcelSteel](#6) against a single-screen auger like the [Norpro](#5), which needs extra screens sold separately for berries and salsa.

Whichever you choose, look at the warranty and at which parts are metal. Plenty of mills ship with a plastic catch cup, and that cup is the part that cracks first, often in the second season.

Do You Need a Mill at All? Prep Paths and Alternatives

The most common question in canning forums is whether a food mill is required, and the answer is no. It is required only for a specific product, and understanding that saves you money and an afternoon.

Whole and halved Romas never need a mill

Most tomato canning is whole or halved Roma in a hot-water bath, and that is the method the National Center for Home Food Preservation testing supports. No milling, no peeling, no discarding of solids. If that is what you are doing, a mill adds work rather than removing it, and a simple [pressure canner guide](https://thegoodatheist.net/best-home-canning-pressure-cookers-for-canning-and-preserving/) covers the equipment you actually need.

A mill earns its place when you want sauce, salsa, passata, juice, or a smooth jam, because those products need the skins and seeds out and a blender cannot do it properly. It also earns its place if you want the solids, since a mill keeps the pulp and returns only skins and seeds to the waste stream.

Raw, blanched, roasted or frozen: four prep paths

You do not have to boil a hundred pounds of tomatoes before milling them. There are four workable prep paths, and they suit different mills and different flavors.

Raw fruit works in a low-speed auger strainer such as the [OMRA](#3), which is rated for fresh or cooked tomatoes, and it is the fastest route because there is no blanching pot. A blade mill will fight you with raw fruit. Cooked fruit, whether blanched in boiling water or simply simmered until soft, is the reliable path for every hand mill on this list. Roasted fruit, blistered under a broiler with the skin side up, gives you a deeper, smokier sauce and loosens skins so they strip off easily before milling. It is a normal part of many home canners’ workflow and worth trying once. Frozen and thawed fruit works, but it softens so much that it clogs fine discs, so use a coarse or medium setting and expect a thinner output.

One caution: auger-style machines and raw fruit is a common source of stalled augers. If you own a Norpro or Foley-class machine, cook or thaw first.

Alternatives to a food mill, ranked honestly

A stand mixer strainer attachment works and handles a reasonable batch, but the small hopper and constant feeding are the complaints that push people toward a dedicated mill. A chinois and a fine mesh sieve give you the smoothest possible passata because nothing pushes pulp through, and it is the right tool for a small batch of a very fine sauce. It is slow, it is tiring, and it does not scale past a few pounds.

A blender purees in seconds and leaves the seeds and skins in, which is the exact problem you are trying to solve. Some canners strain a blended batch through a mesh sieve afterward, which doubles the work rather than removing it. A tomato press, like the [CucinaPro](#10), is fast for a small batch and exhausting for a large one.

The honest ranking for most home canners: a food mill for sauce and any volume above 20 pounds, a blender plus sieve for small batches of very smooth sauce, and nothing at all for whole tomatoes.

Canning Safety for Milled Tomatoes: Acidity and Tested Recipes

Read this section even if you skip everything else. Milling tomatoes is a food safety decision, not just a texture decision, and it is the part of this topic that most roundups leave out.

Tomatoes are a low-acid food, which means they are not safe to can in a water bath without a tested acidification step. Tomatoes are also inconsistent: vine-ripened fruit is noticeably more acidic than field-ripened fruit grown in a hot year, so you cannot rely on the tomatoes themselves to protect the jar. That variability is exactly why the National Center for Home Food Preservation and USDA tested recipes exist, and why you should follow one rather than adjusting to taste.

Milling and pureeing makes the risk greater, not smaller. Breaking tomatoes down releases the pulp, mixes in the seeds, and raises the pH of the finished product, so a milled sauce is less acidic than whole tomatoes in the same jar. That is why tested recipes for tomato sauce call for bottled lemon juice or citric acid, and why you add it according to the recipe rather than to your own judgement of how sour the pot tastes. Bottled lemon juice has a standardised acidity that fresh lemon does not.

Three rules cover most of it. Follow a tested recipe from NCHFP or a reputable canning authority, in the jar size and processing time it specifies. Add the required bottled lemon juice or citric acid. Do not improvise processing times, do not reduce vinegar or lemon juice, and do not add extra water to dilute acidity.

If you want to understand this before you start, our [food preservation and dehydrating guides](https://thegoodatheist.net/food-dehydrators-for-jerky/) cover the storage side of the same season. When in doubt, follow the tested recipe. This is not a place to be creative.

Cleaning and Storing a Mill After Tomato Season

Cleaning is where most people judge a mill badly, and mostly because they are doing it in the wrong order. A few habits turn a twenty-minute scrub into a five-minute rinse.

Clean the mill mid-session, not only at the end. Dried tomato pulp in the perforations takes far longer to soak through than pulp you rinsed while it was still soft. Run warm water through the machine the moment you finish a load, in the direction of the cranking, and most of the seeds and skins leave immediately. Push any stubborn solids through with the included spoon or pusher rather than your fingers.

For the discs, a baking soda soak in warm water does most of the work, and a narrow bottle brush gets into the holes no cloth will reach. Air dry the discs and the screen completely before putting them away. Trapped moisture against a metal screen is what produces the surface rust owners report on chrome-plated parts, and it is entirely preventable by leaving them on a rack overnight.

Store discs loose rather than stacked, and keep them away from a damp cloth in the drawer. If your mill has an aluminium head, wash that part by hand even when the rest of the machine is dishwasher safe, because detergent and acid accelerate the discoloration owners complain about. Doing these five things at the end of every session is the difference between a mill that still works in year ten and one that gets replaced in year three.

Frequently Asked Questions

Which Food Mill Should You Buy?

If you want one answer, the Hungry Artisan 3-Disc is the food mill for canning tomatoes we would put in front of most people. Three discs, stainless throughout, no power cord, and the highest review volume of any disc mill here. If your counter space is the constraint, the OXO Good Grips gets the same job done over a stockpot and folds into a drawer when the season ends.

If you are processing real volume, the Weston Deluxe electric strainer covers up to 80 pounds a session, and the OMRA Spremy covers a bushel at a time and takes raw fruit without blanching. If you preserve apples, berries and potatoes as well as tomatoes, the Mirro Foley and the ExcelSteel are the two multi-function discs worth building a kitchen around. If you are making a handful of jars a year, the CucinaPro press is the honest purchase and everything larger is money you do not need to spend.

Whatever you choose, follow a tested recipe from NCHFP or USDA, add the bottled lemon juice it calls for, and read the safety section above before your first jar goes into a boiling water bath. Then start the season, and update this guide for 2026 as the models change.
