Jiao Quan are deep-fried rings of dough, similar to savory doughnuts but smaller, denser, and incredibly crisp. Each ring is about the size of a bracelet, with a golden-brown color and satisfying crunch. They're the classic pairing for douzhi — the sourness of the drink cuts through the oiliness of the fried pastry. Jiao Quan are also eaten on their own as a snack or crumbled into congee for texture.
Jiao Quan have been a Beijing breakfast staple for centuries, mentioned in Qing Dynasty culinary texts. They were traditionally made by street vendors using a special twisting technique.
