Natto (納豆) is fermented soybeans, one of the most popular but divisive foods at the Japanese breakfast table: it has a strong, ammonia-like smell and a sticky, stringy texture. It is in fact rich in protein, vitamin K2 and probiotics, and with rice it makes a balanced, filling breakfast.
Take the natto out of the pack and stir it vigorously with chopsticks for 20–30 seconds until it is sticky, stringy and foamy (this gives its flavour and texture).
Add the sauce and mustard and stir for another half minute.
Put the hot rice in a bowl.
Pour the natto over the rice and top with the spring onion and (if using) the egg yolk.
Garnish with strips of nori and sesame oil.
Mix straight away and eat warm.

Tips
Stir it thoroughly: the more you stir, the creamier and more flavourful it gets.
For beginners, start with a little natto and plenty of mustard, soy sauce and spring onion.
Natto keeps for 1 month in the freezer.
The strong smell fades over time.
Frequently asked questions
Why is it so sticky?
Polymers (polyglutamic acid) from the Bacillus subtilis fermentation give the stringy texture.
