My husband has become a cookie-making-machine, and last night he discovered mid-batch that we had run out of brown sugar. He thought he could just skip it; I thought he should find a different recipe or use white sugar. We compromised and made a quick trip to the store. Tonight I was making soup and realized I was out of curry powder. I had some curry paste, but had been burned by adding too much paste in previous situations, so had to consult Google just to be certain I could use it.

Cooks Recipes provides many charts, including common food substitutes, temperature charts (for meat and candy), and food yield charts. The University of Illinois Extension Office provides another substitution chart, as well as equivalent charts, but focuses a bit more on nutrition than the previous. The Cook's Thesaurus, another neat tool, is a searchable encyclopedia that contains pictures, pronunciations and background information on many ingredients and kitchen tools, in addition to providing preparation tips and substitution information.
