Can you even create a recipe from scratch after you've learned the recipe from somebody else, will it not always be a derivative work at best, and a copy at worst? Sure, you can add or remove an egg, or change the order or when to add salt or pepper, but an omelette is an omelette.
By that reasoning, everything I will ever create is a derivative work. Which philosophically might stand up to scrutiny, but hopefully doesn't make me a walking infringement.
