Spite Food

I read (on the Wait Wait Don't Tell Me blog) that KFC introduced the Double Down because of complaints that there wasn't enough chicken in their chicken sandwich. If true, it places the Double Down in that delightful genre, Spite Food.

Potato chips are the best-known example of Spite Food. To quote the Wikipedia article:

"The original potato chip recipe was created by George Crum, the son of an African American father and Native American mother, in Saratoga Springs, New York on August 24, 1853.^{[citation needed]} Fed up with a customer who continued to send his fried potatoes back complaining that they were too thick and soggy, Crum decided to slice the potatoes so thin that they could not be eaten with a fork. As they could not be fried normally in a pan, he decided to stir-fry the potato slices. Against Crum's expectation, the guest was ecstatic about the new chips."

I'm still hoping to eat one of those Double Downs; haven't got to it yet.
