There's nothing wrong with having a recipe for filet mignon in the [[filet mignon]] article, or for [[scramble eggs]], etc.
"How to" articles can be neutral and informative.
It's only if we can't manage recipes due to edit wars that we would have to resort to WikiBooks. Suppose Anthere wants to use lots of butter in all her recipes, but Daniel (mav) prefers vegetable oil. To prevent a fight, we could link to Anthere's Guide to French Cuisine and Daniel's Healthfood Cookbook at Wikibooks.
I oppose deleting material from the Wikipedia, just because it fits an identifiable category. The only "fork" I've seen so far that makes sense to me is the dictionaries. There's a clear distinction between "defining a word" and "writing about a subject". But there's nothing wrong with describing the process of stirring eggs so the yolk breaks and mixes the white -- unless you're a segregationist! ;-)
