I'd love a way to find out the various things I can make with certain ingredients. For instance, I have lots of ginger as a result of spontaneous gifts from trees. I could comb through the various recipes for each of the appliances I own, but how much nicer to have a tool that scans my inventory of food and gives me the various recipes that ingredient goes into when I click on it. Maybe one of those clever programmers fiddling with the API can figure out how to do this?
