Beside the basic knowledge, here are some tips for making sure that jars seal, and stay sealed, so you can safely enjoy the bounty of the harvest all year long:
Canning lids are ‘one trip’; they are for one canning use only.
Wash jars and lids in warm soapy water and rinse prior to use. Inspect jars for cracks or nicks, especially on the sealing surface. Set aside any lids where the plastisol (sealant) has pulled away from the lid.
Follow manufacturer’s directions for pre-treating lids Some brands no longer require preheating, while other manufacturers may still require this step.
Clean sealing rim and apply metal band finger-tip tight. The purpose of the band is to hold the lid over the jar opening, not to seal the jar. Air needs to escape from under the lid during canning! Tighten the band until you feel resistance. Over-tightening the bands risks jar breakage or seal failure.
