Çäkçäk, frequently anglicized as chak-chak, is a Tatar sweet. It is particularly popular in Tatarstan and Bashkortostan, and is recognized as Tatarstan's national sweet in Russian Federation.
Çäkçäk is made from unleavened dough cut and rolled into hazelnut-sized balls, which are then deep-fried in oil. Optionally hazelnuts or dried fruits are added to the mixture. The fried balls are stacked in a mound in a special mold and drenched with hot honey. After cooling and hardening, çäkçäk may be optionally decorated with hazelnuts and dried fruits.
