- What is the white layer on the beans?
- That is the biofilm of the Bacillus subtilis bacteria performing the fermentation. It is completely edible and very healthy.
- It's too slimy, what should I do?
- This is the essence of natto (neba-neba). If it bothers you, mix it with hot rice, which dissolves the texture slightly.
Japanese natto with karashi mustard & spring onion
Natto is Japanese gastronomy's 'love it or hate it' dish: fermented soybeans famous for their sticky, stringy texture and distinctive smell. This probiotic bomb is incredibly healthy. The secret lies in the stirring: the longer you stir, the frothier and tastier it becomes. The sharpness of mustard (karashi) and the umami of soy sauce tame the character of the fermented beans.

Instructions
1
✓
Place the natto in a small bowl. Before seasoning, start stirring vigorously in a circular motion.
Tip: Stirring introduces air, causing the sticky substance (polyglutamate) to turn white and frothy, improving taste perception.
2
✓
When it is whitish and very stringy, add the mustard, soy sauce, and lemon juice. Mix thoroughly.
Tip: Acid (lemon juice) and salt (soy) slightly modify the slime's structure and taste.
3
✓
Stir in the crushed garlic.
4
✓
Sprinkle the top with finely chopped spring onion and coriander, and season with pepper.
Tip: The crunch and pungency of the onion counterbalance the soft beans.
5
✓
Serve on top of hot rice, or on its own for breakfast.
Tip: The steam from hot rice intensifies the aromas, so be prepared for an intense experience!
