Anyone who makes preparations for the winter knows that jars of canned vegetables need to be turned over and wrapped in a blanket.
But few people know that this should not be done with all banks.
Which jars should not be turned over?
Never turn over jars with twist-off lids.
This type of lid has a special polymer ring that expands under the influence of the hot contents of the can.
This way, the lid automatically seals the container tightly.
If you turn a jar with a twist-off cap upside down, the lid will be at the bottom, in the coldest place, because heat rises.
