Quick Answers
After processing, I pushed the lid down to make the jar seal. Is this okay?
The lid, or flat, of the two-piece canning lid should
never be checked or disturbed until 12-24 hours after
processing. At this time, if a lid appears unsealed, but
remains depressed when pressure is applied, it has
formed a weak seal. You have two alternatives. You can
refrigerate the food and use it within several days. Or,
you can give the seal a tougher test:
- Remove the screwband and set the jar in a pan
padded with a clean towel.
- Lift the jar by the sealed-on flat.
- If the seal is too weak, the weight of the jar will
break it and the jar will drop and spill leaving the
flat in your hand. The towel prevents the jar from
breaking.
- The spilled contents can be collected for serving
or reprocessing.
- If the flat remains attached, the seal is good.
