Why I wipe the rim before I put the lid on the jar

The jam is already in the jar — and a sweet trail runs down the rim, the threads sticky. Easy to twist the lid “as is”: by the next opening a crust sits on top, mould clings to the sugar, the lid does not sit tight. I wipe the rim at once with a dry cloth or the spoon — and only then bring the lid to a click.

Why I wipe the rim before I put the lid on the jar. Cooling jam before the lid is about steam under the glass; an opened jar in the cold is about a spoon already started; finishing our own jar is about a row on the shelf. Here it is only the rim: clean threads, not a sweet puddle under the lid — not a speech about a new set of jars from the aisle.

If I already clicked it onto sticky — I open, wipe the rim and the inside edge of the lid, and click again. I don’t bath the jars in ice water. This note is only the jar already filled at ours, not a shop comparison of sugar.

I don’t need a lid on a sugar crust. I need a clean rim and a quiet click. In your kitchen is the rim wiped before the lid — or already twisted over a sweet trail?
