My opinion:
Recipes are not per se encyclopedic. However, certain (reasonably
well known) *dishes* are encyclopedic, and part of a good article on
an encyclopedic dish is a recipe, which should be carefully chosen to
be representative / traditional. E.g. there should be a Wikipedia
article on [[Coq au vin]], and that should probably include a
traditional recipe for making it.
Recipes in general, though, should go in some form of WikiCookbook,
probably to be hosted at Wikibooks.
