Whether you are an avid gardener or merely like to stock up on produce when it’s in season, you’re going to need some way to preserve your bounty in order to avoid wasting it. Canning is a low-cost way to preserve a variety of foods in a way that maintains both vitamins and minerals. It is also fairly simple to do, and nothing beats opening up your pantry on a cold winter’s day to find jar after jar of jam, tomatoes, and pickles that you put up yourself.
A water bath canning set is one of the simplest ways to begin your own canning adventure. These often include all the tools — and often the cookware — necessary to put up your own preserves. While canning sets are less expensive than buying the tools separately, the included tools and their materials will vary from one set to the next.
This guide will introduce you to canning sets and describe what elements of a set you should be aiming for when you’re in the market for one. We check out what you can expect at various price points for canning sets and highlight some of our favorite sets.
There are two basic configurations of canning sets that you will run across: those that ship with a pot used for the water bath that is essential to the process, and those that do not. If a set does not include a pot, you will need to provide your own. Luckily, any stock pot with some form of wire rack in it will suffice.
If a set does ship with a pot, know how large it is. These generally run in the 18- to 21- quart size, which is large enough to process around 7 quarts of food at a time. The larger the pot, the faster you can process food. The trade-off here is that a super large pot may be difficult to use and store.
The majority of pots are constructed from porcelain enamel over steel. While this will usually result in a fairly thin bottom and sides, it does provide for decent heat distribution, allowing the pot to heat quickly. Elements of a pot to keep an eye out for are sturdy handles and a domed lid to help trap heat.
Beware of any pot that seems to have problems with enamel chipping.
Jar racks — or lift screens — are an important part of a canning set and should be included with all sets that also feature a pot. If you are providing your own pot, you should also find some form of rack to use within it.
A jar rack holds the jars as they are processed in the water bath. Jar racks are vital for keeping a consistent temperature around the jars and for keeping the jars away from the bottom of the pot where they can overheat and either harm the food you are trying to preserve or break the jar itself. A sturdy wire rack can also be used to lift the jars out of the water bath at the end of the processing period.
While the tools can generally be run through your dishwasher (use the top rack), the pot may be another matter. Since dishwasher detergents can damage enamel, some manufacturers recommend washing a canning pot by hand.
When you’re not using it, how easy is the canning set to put away? The best sets are designed so all parts can easily fit within the pot. Not only does this take up less space, but you will also be less likely to lose various tools.
Canning set tools have one important function: to keep you from scalding yourself during the canning process. To this end, tools are often coated for additional protection from the heat. Tool sets will vary both in terms of the type and number of tools included. Some common canning tools that will likely be in any set you consider include:
Some tool sets will also include additional tools such as tongs for handling hot food and digital timers to process food correctly.
While not standard, some canning sets go the extra yard by including extras such as:
Water bath canning sets can start out at under $15 and can reach upwards of $50 to $60.
At the lower end, you’re generally only buying a tool set. You will need to provide your own pot and rack. Tool sets start out around $10 and can reach $15 to $20 or higher for a quality set.
More expensive sets will include a pot and rack. You will also tend to find a higher quality all around in addition to more tools and accessories. Sets costing around $60 may include extras such as a colander or blanching pot.
Q. Do these canning sets work on an induction range?
A. The majority of water bath canning pots on the market are constructed from porcelain with a metal center. As such, they should work with an induction range. We recommend consulting the manufacturer if you have any questions about induction compatibility, however.
Q. What is the difference between water bath canning and pressure canning?
A. The two primary methods of preserving foods by canning are water bath canning and pressure canning. Water bath canning is a lower temperature process and is ideal for preserving high acid foods. This is the preferred canning method for foods such as salsas, fruits, jams and jellies, tomatoes, pickles, and condiments. As the name implies, pressure canning uses pressure — usually with a specialized pressure cooker — to achieve a higher temperature. This is really the only safe canning way to preserve low acid foods such as meats, vegetables, seafood, and chili.
Q. Can I use a canning set pot to cook down jam or tomato sauce before canning them?
A. While these pots are highly effective for creating water baths used in the canning process, their design — thin bottoms with high sides — will likely lead to scorched sauces, unless you want to stir the pot every few seconds.
