Natto! Fermented Soybeans

Natto (納豆) is one of the few soyfoods which has always been called by its native name in every European language, probably because no equivalent could be found. Most fermented soy products are cultured with molds, but natto is made by fermenting cooked whole soybeans with a bacterial starter (Bacillus natto).
