Generally, when making moldy tofu, it is necessary to let the mold ferment and grow on the tofu first. At this time, tofu will grow long hair. Generally speaking, as long as you see a thin layer of white hair on the surface of tofu, you can pickle it. The time is usually around 7 days.
Generally speaking, the higher the temperature, the shorter the fermentation time. It is suggested that the time can be increased or decreased according to the specific weather temperature. Otherwise, the fermentation time is too long, which may make the moldy tofu sour and deteriorate.
Fermentation environment of moldy tofu
1, high temperature, high humidity and poor ventilation conditions: Moldy tofu is a fungus fermented food, and the white hairs on it are Mucor fungi, which belong to heterotrophic aerobic fungi and need to grow in a high temperature, high humidity and poor ventilation environment. It is recommended to put it in a humid and poorly ventilated environment with a temperature of 20-25℃ at ordinary times.
2. Cover with straw: Mucor fungi on moldy tofu mostly exist in soil, straw and air, so it is suggested to cover the tofu with a layer of straw when fermenting moldy tofu.
