I haven't commented on recipes before, so I'll just say briefly: Good recipes are great, dense sources of information. They are important parts of any good description of a given dish. So any dish which is deserving of an encyclopedia entry should include at least one recipe, if not one for each culturally significant variant.
Example: http://www.flickr.com/photos/bertrand_sereno/550528/
Choosing one recipe to represent the collection of possibilities for a dish is no more POV than choosing one quote to represent a poem, book, film, or famous wit. The thought of recipes being banned from WP [by people who clearly know nothing about them, nor have any idea of the number of significant literary works inspired by or devoted to recipes] gives me indigestion.

[ As with any new type of content, there is a need for good models of encyclopedic usage for others to follow. Suggestions from recipe lovers? ]
