I never knew the lids could be reused - do you have to do anything special other than resterilize them?
Lol, I should have been more specific. I only use lids once, but I have used lids that I’ve found in my grandma’s basement that were around 30 years old.
Don’t ever reuse lids (AKA flats). Maybe the bands (rings) a year or two but not the lids. I lived around hillbillies for years, gardened and safely canned. They don’t reuse lids, either.
Stock up on lids for years ahead. They’re cheap. Use new lids each year. If the rings (bands) and jars are okay (not warped, mashed, cracked, etc.), they should be safe (after yearly visual inspection). And don’t hot bath tomatoes (that is, don’t cook them without a good pressure cooker). That was done in the days of tomatoes with much higher acidity (but no more).
Get a good and recently published book on safe canning, and follow every instruction to the letter. The USDA might also have a current publication online for canning.
