Here is what the Government just emailed me (I sent almost the
identical question):

"No. Recipes or formulas are not protected by copyright. It is only
when a recipe is accompanied by substantial literary expression in the
form of an explanation or directions, or when there is a combination of
recipes, as in a cookbook, that there may be a basis for copyright
protection. Even then, it does not protect the listing of ingredients
or prevent others from preparing the recipe.
