Why a recipe’s method is hard to copyright
Copyright is designed to protect how an idea is expressed, not the underlying idea or practical method. A recipe’s ingredient list and directions usually describe a process for making food, so another person can often write those instructions in their own words and use the same proportions and steps.
That distinction matters because a recipe has to communicate what to do. Copyright can cover a cookbook author’s distinctive prose, photographs, illustrations, or the book’s original arrangement—but it generally does not give the author exclusive control over the dish itself or its functional instructions.
What can still be protected
Copying a recipe page word for word, including its expressive introduction or headnote, may raise a different copyright issue than independently describing the same cooking method. A cookbook’s selection and arrangement of recipes may also receive protection as a creative compilation, even though that protection does not make each recipe exclusive.
A recipe kept secret may be better suited to trade-secret protection: legal protection for valuable information that its owner takes reasonable steps to keep confidential. That can work only while the information remains secret. Once a recipe is published or readily discoverable, that advantage can disappear.
So a cookbook writer may be able to stop someone from reproducing the page as written, but not necessarily from cooking the dish—or explaining how to make it—in new words.
