Preparation materials: old tofu 1 block

Steps:

1, the plate with plastic wrap to prevent oil on the plate (once there is oil, the fermentation can not be up), the washed tofu on the plate wrapped in plastic wrap.

2, the plate is also wrapped in plastic wrap and pressed on the tofu, the plate on the pressure of a bowl of water. Press the water out of the tofu. Pour the water once every half hour, four times.

3, press the water dry, cut the tofu into cubes.

4, the cut tofu emissions neatly placed in the box, each piece of tofu to leave a little space to facilitate fermentation.

5. Wrap the tofu in tinfoil, not too tightly. Put the tofu in a cool place to ferment for three days, open the tinfoil once a day to change the air. (Three days after the tofu will have mucus on top, if the temperature is high enough there will be yellow hairs on the fermentation success, but if you find black spots on the tofu means that the fermentation failed to be thrown away)

6, three days after the tofu fermentation success.
