Hamantashen - 3x3in Vinyl Sticker - Waterproof Cute design for Purim! Purim is a joyous Jewish holiday that celebrates the miraculous events told in the Book of Esther. A symbolic food eaten during the holiday of Purim is hamentaschen (“ears of Haman”). Haman is the villain of the Purim story (more on that below). This triangular-shaped cookie is supposed to represent either Haman's ears or his three-cornered hat. The center of each “hat” is filled with jam or sweet filling.
