I have an ongoing dispute with a co-worker about what a galette is. I define it as something baked on a crust (like a tart or pizza), that can have any particular shape or size. It's the same definition as the Food Lover's Companion and The Chef's Companion. My co-worker insists that there's another type of galette. He says my version is the PASTRY version. Anybody else have another definition WITH A SOURCE? Also, according to this definition, wouuld you say that a pizza or a tarte tatin is a galeete?
