Recipes are a special case, and it could depend on what you mean by "recipe".
What is protected by copyright is "expression", not "information", and that can be a difficult distinction for some people to wrap their heads around.
Given that, I'll simply quote the US Copyright Office on this one:
http://www.copyright.gov/fls/fl122.html
Mere listings of ingredients as in recipes, formulas, compounds or prescriptions are not subject to copyright protection. However, where a recipe or formula 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, there may be a basis for copyright protection.
Consider these two recipes for scrambled eggs:
Recipe A:
Ingredients:
2 eggs
oil
Directions:
Beat eggs
Fry in oil over medium to high heat
Recipe 2:
When I scramble eggs, I like to first put some olive oil in a frying pan and heat it to just above medium. You have to be careful if you are frying with olive oil, because the fats in it will burn at a lower temperature than vegetable oil, so you can't fry at as high a temperature than you can with vegetable oil. Now, I know some people like to use a whisk and mix in some milk, for fluffy eggs, but I don't like my eggs fluffy and uniform, and I prefer a more "marbled" appearance and meatier texture. So, I crack the eggs right into the pan and then use a spatula to mix the eggs while they are frying. I also sprinkle in just a little bit of salt, and coarsely grind some black pepper into the eggs before turning them over.
Okay, so there are two things that someone could call "recipes". Can you guess which one would be more likely to qualify for copyright protection?
The first correct answer will receive my recipe for deep fried twinkies and a prescription for Lipitor.
