Put the processed bean koji into the tank until it is 80% to 90% full, compact it layer by layer during filling, and place it in a constant temperature room at 28°C to 32°C for heat preservation and fermentation. The fermentation time is controlled at about 15 days.

I cooked 8 taels of dried soybeans for the first time. The beans cannot be boiled casually. They must be cooked until they are soft and turn into powder when twisted. Reference time: My 8 taels of dried soybeans were soaked in advance and cooked in a stainless steel steamer for 2 and a half hours after the water was boiled. It is steaming and warm from morning to night every day, which is conducive to the fermentation of tempeh. In addition to the stove house, every family also has a fire house, which is also warm.

You can cover the tempeh thickly and leave it alone, it will ferment naturally. But now we only have electric heaters and the room temperature is not enough, so it is not very convenient to make tempeh, so we can only use a fermentation box.

How to make tempeh:

Soak the soybeans in warm water in advance. Now I take out the soybeans soaked last night and clean them. Then put it on the stove and cook for two hours. Everyone must remember to make this tempeh and keep all utensils away from lard. Now add the soybeans to the pot and cook for two hours. After it's cooked, we take it out and let it cool to about 40 degrees.

Pour out the soybean soup and let it cool down a bit. Do not throw it away. Put this soup into a jar and sprinkle with a little salt. Seal the lid with plastic wrap for easy storage. Spread gauze, a layer of plastic wrap, and a layer of banana leaves. Finally, pour the tempeh on the banana leaves, wrap it up, and put it in a basin.

In the evening, use a basin of warm water, about 40 to 50 degrees Celsius, and put the beans on it, and put a basin on top to keep it warm. On the fourth day, I already smelled a strong smell of tempeh. Tempeh smells stinky enough. Pour it into another basin, add a little more salt to this one, and add white wine to kill the bacteria. Then mix it evenly and add a little spicy pepper. Finish.
