Jessica Seinfeld’s Deceptively Delicious is unoriginal, but it’s not plagiarism.

Copyright protection is weak when it comes to recipes. The U.S. Copyright Office states, “Mere listings of ingredients as in recipes, formulas, compounds or prescriptions, are not subject to copyright protection.” Explanatory notes—like the paragraph before the recipe where the author reminisces about dinners on the family farm—are protected, but the recipe itself is not. That’s why Colonel Sanders has had to work so hard to keep his recipes a secret.
