What is "nattō"?

Nattō is a traditional Japanese food made from fermented soybeans that are rich in protein and nutrients. The soybeans are first cooked and then fermented with a special bacteria called Bacillus subtilis nattō, which gives the beans a slimy and sticky texture. Nattō is typically served with soy sauce, mustard, and chopped scallions, and is often enjoyed as a breakfast food or as a side dish with rice. It has a strong and distinctive flavor that is often described as nutty and pungent. Nattō is a popular food in Japan and is believed to have many health benefits, including improving digestion and promoting cardiovascular health. It is also a popular ingredient in Japanese cuisine and is used in a variety of dishes such as sushi rolls and salads.
