Recipes - Copywriteable or not?

Ok, so copywriteable is not really a word.  But you get the idea

Interesting post at the Volokh Conspiracy about an issue I blogged about here.

The post concludes with this .... Cookbooks, full of recipes that can be readily found (copied) on the internet, would seem to be a great candidate for a music industry-style economic implosion. But in fact, the cookbook industry is booming. Can you guess why?

I agree with the factual statement that both cookbooks and copying of the recipes on the internet are occurring.  Yet for the life of my I can't understand why.  With the internet, and handy tools such as Evernote, just why would you buy a cookbook?  What does it offer of value?     Yet they still sell.
