How to make Natto (Recipe) |
|
| |
- Soybeans shall be soaked in the water, until the bean stop swelling.
It takes one night in summer. It may take one full day in winter.
- Steam or boil the soybeans until the beans become soft. (Recommend
to steam., if boiled, the taste of the soybean flow out to water and the
thin skin of the bean peels off, and also recommend to use a pressure cooker,
otherwise it takes several hours to cook.)
- Put the dried straw into boiling water several minuts to sterilize
(Natto bacillus survive in 100C(=212F) hot water more than 10 minuts)
- Prepare the straw as a package. Probably one package for 50g(=1.75oz)
of bean (use enough straw)
- Put the cooked beans on the straw and cover up with the straw and tie
- Keep the package at about 42C(=108F) degree. Usually I put it in the
cooler chest with hot water petbottle.Temperature changes 45C(=113F) to
35C(=95F) and then replace the hot water in the pet bottle (plastic transparent
bottle such as for Coca-Cola ) Please be careful that natto fermentation
requires enough oxygen
- Fermentation will proceed enough in one or two days. Then keep it in
refrigerator.
