The problem is while recipes are facts and can be freely spread, prose about how to make cookies is copyrighted. So you get lots of recipes but the important instructions are losts, and people get used to the idea that a recipe is just ingredients and easy to follow steps. The results is lots of recipes that are pretty easy follow, but as always when a design meets a user someone is going to misinterpret your fool proof design. So good simple recipes is a lot like UX when the needs are simple. Think: Recorder app vs. Audacity.
