As a fermented food, time breeds its unique flavor, which is actually quite good from the taste alone. However, natto itself has a strong odor, like months of unwashed socks, which makes you sick to your stomach.

Natto, like stinky tofu and tempeh, is a fermented food that is easy and inexpensive to make, and can be made at home by Japanese people, as long as they are hygienic.

First, prepare the right amount of soaked soybeans, add sugar according to your taste, and place them on a steamer for about an hour until the beans are completely soft. Then let the beans cool, add the right amount of pure water and natto bacteria, mix well and put in a special container to ferment for 20 hours, delicious is ready. Many people like to use a yogurt maker as a fermentation vessel, which allows for a more complete fermentation and a faster time.
