Mandelbrot, also known as Jewish biscotti, is a delicious treat that can be enjoyed during Purim. These twice-baked cookies are made with a dough that includes ingredients like flour, sugar, eggs, and almonds. The dough is shaped into logs, baked until golden, and then sliced and baked again until crispy. Mandelbrot can be flavored with various ingredients such as chocolate chips, dried fruits, or spices like cinnamon. These crunchy cookies are perfect for dipping into a cup of tea or coffee.
