Quick Answer
Essential equipment for water bath canning includes a large pot, canning jars, lids, and rings, a lid lifter, and a candy thermometer.
Canning Jars, Lids, and Rings
When selecting canning jars, choose ones that are specifically designed for canning and are made of tempered glass. The jars should have a wide mouth, allowing for easy filling and cleaning. A dozen jars with lids and rings should be your starting point, but consider purchasing additional sets to keep on hand. Lids should be new, and rings should be in good condition. Before use, wash jars, lids, and rings in hot soapy water and sterilize them in a pot of boiling water for 10-15 minutes.
The Water Bath Canning Pot
A large, deep pot with a heavy bottom is ideal for water bath canning. The pot should be at least 3-4 quarts in size to allow for 1-2 inches of water above the jars. A pot with a rack or steamer basket will help keep jars off the bottom and prevent breakage. Avoid using a small or shallow pot, as this can lead to uneven heating and potential breakage of jars. When selecting a pot, consider one made of heavy-duty materials, such as stainless steel or enameled cast iron.
Additional Tools and Accessories
A lid lifter is a handy tool for removing hot lids from the pot. This tool can be purchased or made from a metal or silicone utensil. A candy thermometer is also essential for accurately monitoring the temperature of the water bath. When using a thermometer, ensure the probe is fully submerged in the water, and the temperature reads between 212-215°F for water bath canning. Other useful items to have on hand include a jar lifter, canning funnel, and a clean towel for drying jars.
