This is a handy tip I love to use to keep only fresh foods in the refrigerator. It’s a challenge to know when food is still good or has been sitting in the refrigerator for a month. You don’t want to waste food.
Keep track of food by writing the date that you open the package with a marker. Put older foods on the top shelf to remind yourself to use them first.
It’s that easy. This is best for pasta sauce. Somehow we collect sauce and I never know when they were opened. This really helps us keep track of food.
