Use by dates - - -
My aunt was very unhappy when my cousin (her daughter) cleaned out her refrigerator and tossed out everything that was "expired" - only if by a few days or so!
I tend to use "judgement" when it comes to expiration dates - if it's something like milk - it smells and tastes bad - no problem there.
When it comes to spices and condiments - I probably should be embarrassed by how old some of those things are. I think the new packaging has a "best if used by ____" dating on the packages now. Some of the older ones have some kind of code.
Anyone else keep and use outdated stuff?
