There are plenty of sites that offer databases of recipes, searchable by ingredients. Cookin' With Google takes the wider approach, harnessing Google's custom search power to return recipes from tons of food-focused sites. It's just like performing a standard Google search, and has the same powers and limitations. Too many specific terms, and you'll narrow your results into oblivion. Just entering "lemon," though, is overwhelming. As the site itself suggests, combine a few ingredients and maybe a cuisine or technique—braised, fried, barbecue—and you'll get a wealth of intriguing responses from sites like Epicurious, Chowhound, Recipezaar, and many others. Our previous picks for clean-out-your-fridge recipes have included Five Mushrooms and RecipeMatcher, and Cookin' With Google earns a spot next to them. Free to use, no sign-up required.
