Sure - as I said, partly tongue in cheek. The problem is really that as a cooking-ignorant person, it's work to figure out if a recipe is going to be time consuming, expensive, or require obscure, or (to the naive palate) unpleasant ingredients. I've no problem with other people doing whatever floats their boat, but if the app is supposed to be an easy introduction to cooking it should at least place that stuff behind a flag of some kind.
