Kreplach are dumplings that are commonly served during Purim. They are made by rolling out a thin dough and filling it with a mixture of ground meat, onions, and spices. The dough is then folded over the filling and sealed, creating a small pocket. The kreplach are then boiled until cooked through and served in a flavorful broth. These savory dumplings are a delicious addition to any Purim meal.
