Which canning jar is best?
If you have an abundance of fruits and vegetables you want to preserve as long as possible, you’re on the right track to saving money on food in the long run. However, you’ll need a suitable container to store your goods until you’re ready to eat or use them.
Canning jars are designed to keep food fresh and can even serve as decorations. The best jars, such as the Sewanta Ball Wide-Mouth 32-Ounce Mason Canning Jars, have a stylish design, a large capacity and an airtight seal.
What to know before you buy a canning jar
Water bath canning vs. pressure canning
Using a water bath or pressure canning method, you can store your goods in a canning jar.
- Water bath canning involves sealing food in a jar and boiling it. Once it’s removed from the hot water, hot air is released, creating an airtight seal.
- Pressure canning can heat a jar higher than a water bath can. However, pressure canning requires a pot-like appliance with a ventilation rack and a pressure gauge.
Low-acid foods vs. highly acidic foods
Highly acidic foods such as pickles, jams, jellies and tomatoes can be heated using water bath canning. However, for preserving low-acid foods such as non-pickled vegetables, soups and stocks, you must use pressure canning, as they require higher temperatures to kill bacteria.
Regular-mouth vs. wide-mouth jars
You can store your food in a regular-mouth jar that tapers at the top, giving it a smaller opening than a wide-mouth jar. Some prefer the sleek design of regular-mouth jars, but wide-mouth jars are easier to fill or empty and are suitable for keeping in the freezer as there’s enough room for the liquid from the food to settle after it expands. It’s also easier to clean a wide-mouth jar.
What to look for in a quality canning jar
You can find canning jars in three sizes: 8-ounce, 16-ounce and 32-ounce.
- 8-ounce jars are suitable for small batches of jams or sauces.
- 16-ounce jars are ideal for fruits, vegetables and foods with a thicker consistency, such as relish and pie filling.
- 32-ounce jars are what you need to store large batches of salsa, jellies and small fruits and vegetables.
If you’re looking to store just a few batches of sauce, soup or a small number of vegetables and fruits, you can save money by getting a basic set with three to six jars.
If you want to do a lot of canning, look for a set with at least 10 jars. Some packs come with different-sized jars, so you can decide which one you want to use once you’ve figured out what you want to store.
A glass jar without a lid won’t do you any good, so make sure your set comes with the same number of tops as jars, if not more. Also, bands are a must for your lids, helping ensure an airtight seal.
An airtight seal is essential as it prevents air from entering, preserving your food longer and creating a leakproof fit. That way, even if the jar gets knocked over in the refrigerator, you don’t have to worry about cleaning up a mess.
How much you can expect to spend on a canning jar
You can find a cheap set of canning jars for $10-$20. For jars with a more durable build and elegant look, expect to spend $20-$40.
Canning jar FAQ
Are canning jars ready for use right out of the box?
A. Yes, but sterilize them before you use them — they may be contaminated with bacteria that can spoil your food.
Can I fill a canning jar to the top?
A. It’s not advisable, as it doesn’t allow for a tight seal. For best results, try to leave at least half an inch of space between the lid and the top of the food.
