"Hamentaschen are the triangular filled pastries that are traditionally prepared during the Jewish holiday of Purim. The name hamentasch is usually thought to refer to Haman, the villian of story in the Biblical Book of Esther, who is supposed to have worn a 3-cornered hat. A more likely source of the name is from the Yiddish word for mohntaschen, which means poppyseed-filled pocket. Traditional hamentaschen filling flavors include poppyseed, prune, and apricot. Many hamentaschen are made with cookie-like dough, but this recipe produces a very rich and and tender yeast-raised dough."
