Copyright on a recipe? Give me a break. For one thing, the ingredient shouldnt be protectable, it's just a list, you cant protect stuff like that. As for the recipe itself, there is almost no artistic quality to it at all, there is nothing about the wording that is creative. It's just "heat this" "stir that" etc. If you were to allow copy. on stuff like that then no one would be able to communicate about foods. Everybody would just claim on copyright on everything. I claim scrambled eggs: "Take two eggs, beat them..."
If the writing here had some sort of style to it e.g. "we used to use whiskey then one day in the kitchen a waif told us..." You know something that is not just a set of steps, then that would be protectible but only for the creative content. You would still be able to describe the basic process.
There is still another problem, it is arguable how much wording is needed to copy. The recipe maybe runs 120 words and is borderline, even if it didnt have the problems mentioned above. There was a case involving Madame Curies's letters. The letters were short e.g. 100 words and they were not long enuf to be copy. Most wisdom holds you would need about 100-200 words before you can be sure it would be protectable.
But here the problem is the wording is so basic. If you were to allow copy. on this then no one would be able to communicate about cooking and foster that knowledge. That is not the pt. of copyright, the point is to protect the creative aspect of the wording.
But go ahead, be your own copyright police, keep people from learning how to cook.
