Douhua (豆花 — Silken Tofu Pudding)
National — sweet in south, savoury in north; ancient preparation
Ultra-silken, barely-set tofu served as a dessert or breakfast with sweet ginger syrup (southern style) or savoury toppings (northern style). Made from hot soy milk coagulated with gypsum (calcium sulfate) or glucono delta-lactone (GDL) — producing a texture far more delicate than any commercial silken tofu. The northern-southern divide on sweet vs savoury is a defining Chinese food debate.
