7 Jin of bitter tofu. The shape of Castanopsis sclerophylla fruit is very similar to that of hazelnut, and the size is almost the same. A kilo of bitter tofu can produce seven kilos of bitter tofu.

1, the bitter fruit picked first should be peeled off, leaving white pulp inside.

2. Then wash and polish with water. Slightly precipitate the ground slurry. Here's a trick. You must pour out the water on the surface, or the tofu will become smelly and astringent.

3. After a layer of water is poured off the surface, pour the polished slurry into the pot and boil it. After the slurry is thickened, it can be taken out of the pot and waited for cooling. After the pulp condenses into a ball, the bitter tofu is ready.
