Here's the problem, and I'm ashamed to say it. Much too often, I forget what's in my fridge. The week runs by and suddenly that head of cabbage has been there for ten days! Oops. It's wasteful and it's the curse of a full-size fridge, where things can get pushed to the back and forgotten. So I've been using a new tactic. I keep my grocery receipt and highlight things that need to be used in a timely fashion, or things that I hope to cook with that week. Then I stick it firmly to the front of the fridge, a visual reminder every time I open it. It's sad that I have to resort to this, but my memory is lousy and I simply can't shop every day. This is quick and helps me remember.
What about you? Do you forget about things in your refrigerator or your cupboards? How do you keep track of your shopping and your cooking?
