The Jewish holiday of Purim begins Monday evening, and the signature treat of this holiday is a cookie called a "hamentashen."  KYW Newsradio's Hadas Kuznits chats with Essen Bakery owner Tova Du Plessis -- who was just nominated last week for a prestigious James Beard award for the 4th time in a row -- about how to make these cookies and what she's doing at home and in her bakery to celebrate the holiday.
