You gotta try out Cookpanion. You can do everything recipe related right from Facebook. The mobile app will drop in a month for iPhone, but you can already view their recipes on tablet and mobile for in-kitchen or in-store convenience. It’s good! :D

Cookpanion is a nice new tool that has all of the features of these other apps, but right on my Facebook account. Sharing is the same, lists, meal plans, bookmarks, following other people cooking... It’s a good one. apps.facebook.com/cookpanion/
