Mandelbrot, also known as Jewish biscotti, is a popular treat during Purim. It is a twice-baked cookie that is similar to Italian biscotti. The dough is made with flour, sugar, eggs, and almonds, and then shaped into logs. The logs are baked until golden and firm, and then sliced and baked again to achieve a crispy texture. Mandelbrot is often flavored with cinnamon and vanilla, and can be enjoyed on its own or dipped in coffee or tea.
