These were my first Hamantaschen. What is a Hamantaschen, you might wonder? These cookies are little three-cornered wonders that puff up into bite-size pastries filled with any number of things, including jam, chocolate hazelnut spread, nuts, dates, and perhaps most commonly, poppy seed filling or prunes. Their triangular shape is sometimes called evocative of the ears of the villain of the holiday of Purim - you guessed it - Haman, who is defeated in the story as told in the Book of Esther.
