Sealing canning jars without boiling them may sound like a risky business, but rest assured that the process has become much simpler and efficient now. Jarden, a leading producer of home canning equipment, has stated that heating the lids prior to placing them on the jars is no longer necessary. Here’s how you can seal canning jars without boiling them:
After properly sterilizing your jars, wash the lids and rings in warm, soapy water.
Rinse them off and let them dry completely, and then set them aside.
Fill the jars with your desired food items, leaving about a half-inch of headspace at the top.
Wipe the rims of the jars with a clean, damp cloth to ensure there is no debris or food residue.
Center the lid on top of the jar and twist on the ring until it is finger-tight (not too loose nor too tight).
Place the jars in your pressure canner or boiling water bath and proceed according to your recipe’s instructions.
By following these simple steps, you can seal your canning jars without boiling them and still have a tight and secure seal to preserve your delicious jams, pickles, and other homegrown produce. Remember to always consult your canning recipe and guidelines before proceeding.
