Warm buffalo milk is curdled with ginger juice into a delicate, silky custard. This traditional Cantonese family dessert is gentle, aromatic, and uniquely satisfying.
Thoroughly wash and peel 2 pieces of fresh ginger root. Grate them finely and squeeze through cheesecloth to extract the juice; you need about 2 tbsp of ginger juice.
In serving bowls, pour 2 tbsp of ginger juice into each bowl used for the final set, ensuring all fiber is strained out and only the clear juice remains.
In a small saucepan, combine 2 cups of buffalo milk and 4 tbsp sugar. Warm the milk gently over low heat, stirring until sugar dissolves, and heat to just below a simmer (about 158–167°F; do not boil).
Quickly but gently pour the hot milk from about 6 inches above into the bowls containing ginger juice. Do not stir! This allows the ginger enzymatic reaction to curdle the milk evenly.
Let the bowls stand undisturbed, uncovered, for 5–8 minutes at room temperature until the surface firms into a silky, custard-like curd. Serve immediately, while still warm.
