From Slashfood:

I love chicken, but I have to admit I never thought of eating the cockscomb.

First of all, get your mind out of the gutter. Thank you. The cockscomb (also called “le creste”) are those funny little things on top of the chicken’s head. Eating this probably never occurred to most people, since it would be like eating someone’s hat or maybe fingernails. But people do eat it.
