You keep eating the front of the shelf

The jar you just packed is the one you can see. The one from last October is behind it. That is how a pantry turns into a museum.

A count that goes down when you use a jar is not fancy. It is how you cook on purpose. Open the next batch because the note says so, not because it is in front.

If someone asks how you track what’s in the pantry, that is the answer. Write it once. Mark it used.
