Silky tofu fa with sweet ginger syrup is a delicate, refreshing dessert. A family treat with smooth, custard-like texture and gentle sweetness.
In a small bowl, dissolve the gypsum powder and cornstarch in 3 tbsp of water until smooth. Pour this mixture into a heatproof serving dish, swirling gently to coat the base.
Pour the unsweetened soy milk into a saucepan and heat over medium heat until it reaches about 185°F—do not let it boil. Stir occasionally to prevent scorching.
Immediately pour the hot soy milk from a height (about 8 inches above) into the prepared serving dish with the gypsum mixture. This helps distribute the coagulant evenly.
Cover the dish with a lid or plate, and let it sit undisturbed for 30-40 minutes at room temperature, until the tofu has set with a silken, jiggly texture.
Meanwhile, prepare the ginger syrup: In a small saucepan, add water, brown sugar, and fresh ginger slices. Bring to a gentle boil, then simmer over low heat for 10 minutes. Strain to remove ginger slices.
To serve, gently spoon the tofu fa into bowls and drizzle with the warm ginger syrup. Enjoy immediately for the best texture.
