Noyau (pronounced "nwayoh," and spelled noyaux when plural)
refers to the kernel inside of a cherry or apricot stone.  To
become edible, seed kernels must first be roasted in their pits
to destroy toxic levels of prussic acid. Then, they're smashed
open with a hammer and used in cooking to add a distinct bitter
cherry-almond flavor to dishes. Noyaux can be employed to
enhance ice cream, custard, and amaretti cookies; create the
liqueur creme de noyaux; or give almond extract its signature
flavor. Have you ever heard of noyaux?  Source: Flickr User
