Kai kou xiao

Kai kou xiao (Chinese: 开口笑; pinyin: kāikǒuxiào; lit.

'open mouth laughing') is a fried sesame egg cake found in Chinese cuisine.

With the exception of the sesame seeds, everything else is mixed together, and the resulting dough is cut into pieces.

The chef must lift the frying pan off the stove and put it back on depending on the situation.

The resulting opening crack is where the literal name in Chinese comes from, as it resembles a happy smiling mouth.
