These are the traditional triangular filled cookies eaten for the Jewish holiday of Purim. They are shaped like the 3-cornered hat worn by the bad guy in the story, Haman. The Purim story is from the biblical Book of Esther. OK -- history aside, these are yummy cookies! I tried 5 different recipes for hamantashen this year, and this was by far my favorite. This recipe is ever-so-slightly altered from the original, which is by Flo Braker, pastry goddess. Edited to add: the traditional fillings are spiced prune (lekvar), poppyseed, and apricot. My kids' favorites are cherry and chocolate. Do whatever makes you happy!
