Yield: 1 kg
Fermentation time: 3 to 4 weeks
Difficult: Easy
Ideal Fermenting Temperature: 25 degrees celcius

Instructions

1) The night before, measure the required amount of soy beans and add to a bowl. Add 4 cups of water. Soak overnight for 8 to 12 hours.

2) Drain soybeans. Place them into a pot and add 4 cups of water. Boil, adding more water when needed. The soybeans are cooked when you can easily crush them between your thumb and ring finger. It will take approximately 4 to 5 hours on a conventional stove top or 30 minutes in a pressure cooker.

3) Drain the cooked soybean, reserving 1 cup of the liquid. Transfer the soybeans into a mixing bowl and mash them thoroughly using a masher or pickle packer. Sprinkle all the salt over the beans, add the 1 cup of reserved liquid and mix thoroughly. Allow the mixture to cool below 60 degrees celcius.
