Recipe App Wanted

I'm planning to purchase an iPhone soon and have been searching for applications I might want to get along with the phone. I've browsed through the lists in the iTunes store for recipe and cookbook apps but can't seem to find one quite like what I'm looking for. Are there any available that come without a database of already-installed recipes, or one with a database that's easily erased? What I'd like to use the app for is basically storage and compilation of my own recipes, and occasionally a recipe from another source. I don't want thousands of recipes I'll never use cluttering up the app's database. I could use a notes or memo app for a very basic version of this but something more highly organizable and searchable by names and ingredients (like some existing apps allow) would be fantastic. Any suggestions on apps I could try out, or even a way to do this myself, would be greatly appreciated.
