I am excited to find this thread! I am engaged in a similar project--I am due to move in less than a year, and I am a bit of an ingredient hoarder. I had to move cross-country on about six weeks notice a few years back, and I was mortified by the amount of food I had to dispose of. (Luckily, I knew a couple of poor college students who were delighted to take home a trunk full of free food!) I have done better with the stockpiling this time, but I have a tendency to scoop up interesting ingredients when I see them, plus I get a fair number of food gifts. I am determined not to move more than I have to (it will be local, so not having to box and ship things, but I would like to save myself the hauling).
I am concentrating on the one-offs rather than pantry staples like flour and butter...those I will eat down as the move gets closer. I made a list using Apple's Reminder software, partly because I like clicking the button to cross things off, plus I have it with me wherever I am thinking about menus.
So far a lot of it has just been eating up freezer leftovers, but I did do a lentil soup recipe that cleared out lentils, chicken sausage, and chicken broth, jam bars to get rid of a huge jar of fig jam, and tossing some roasted cauliflower with the end of a jar of chimichurri sauce instead of making an equivalent sauce from scratch. Oh, and today was a baked tofu recipe that cleared out a block of tofu and the end of a jar of peanut sauce.
