Poe’s Law, loosely paraphrased, states that it can be very difficult to tell the difference between parodies of extreme beliefs and sincere expressions of those beliefs.
Confusion of this kind occurred with the 1976 cookbook Cooking With God. The authors, Lori David and Robert Robb, intended it to be, in all seriousness, a religious-themed cookbook. But due to the title, many people apparently assumed it was some kind of joke.
Recipes included Manna Honey Bread, Oasis Stuffed Eggs, Caravan Sweet Potatoes, and Eggs Bathsheba.
