How to enjoy it

Let the filling cool, then break off small pieces; the fine surface is fragile. To ask about the fat, say “这是猪油做的吗?” (“Is this made with pork lard?”).

How it may vary

A LITTLE SOMETHING TO READ

Story & history

The little bubbles of Sanyuan

This account describes a tradition or story, rather than an established historical fact.

This Sanyuan pastry is named for its delicate bubbled surface. Steam during frying lifts the scalded wheat dough into a light, fragile covering around a sweet walnut filling. Huanggui is sugar-preserved osmanthus, adding a floral aroma rather than cinnamon. The pale exterior can hide pork lard in the dough, so a sweet appearance does not make it vegetarian.
