Ma'amoul is an ancient cookie filled with fruits and nuts such as dates, walnuts, and pistachios. The cookies are traditionally prepared for Easter, festivals, and celebrations, and they are typically shaped into balls or domes. In order to differentiate the cookies, the walnut version is usually shaped into a dome with a round top, the date ma'amoul is shaped into a dome with a flat top, while the pistachio ma'amoul has an elongated, oval shape.
