Chak chak is a traditional sweet dessert from Uzbek cuisine. It is made by frying small pieces of dough and then soaking them in hot honey or sugar syrup. The pieces of dough stick together to form a crunchy, sweet treat. Chak chak is often flavored with spices like cardamom or cinnamon, and sometimes nuts like almonds or walnuts are added for extra crunch. It is usually served during special occasions or celebrations, and it is a popular treat in Uzbekistan and other Central Asian countries.
