I recently discovered
http://www.RecipePuppy.com (and
http://www.CookThing.com) on Digg. They're amazing!
RecipePuppy, which also has a Firefox add-on available, lets you search by ingredients for recipes from all over the internet. So, if you want something with shrimp and peas, for example, but can't decide what, you can do a search for all recipes using those two items. Once you get your initial results, you can refine the search by choosing from lists of related ingredients that are displayed to the right of the page. You can click 'I must use this,' 'I have this,' or 'Exclude this.' The Exclude feature is great if there's something you're allergic to/can't stand.
The related site is called CookThing.com. It's basically the same search tool, but instead of searching by ingredient, if you already know what you want to make (pancakes, for example), you just search for that. Then, it gives you a checklist of ingredients you want to use. So, if blueberry pancakes are cool, but you wouldn't want pecan pancakes, you can choose that. Then it does the same search that RecipePuppy does, bringing you all the recipes it finds on other sites. You can then refine the results just like you do with RecipePuppy.
Seriously, I'm having
way too much fun with these sites.

Best things I've ever found on Digg.
