Ingredients
For the Rice
- 2 cups short-grain Japanese rice (about 480 g)
- 2 1/4 cups cold water
- 1/2 teaspoon fine sea salt
For the Natto Bowl
- 4 packages natto (about 50 g each), fermented soybeans
- 4 teaspoons low-sodium soy sauce
- 2 teaspoons karashi mustard (or 1 teaspoon English mustard)
- 4 large eggs yolks (optional, one per bowl)
- 3 scallions, finely sliced on the diagonal
- 1 sheet nori, shredded into thin strips
- 1 teaspoon toasted white sesame seeds
- 2 teaspoons toasted sesame oil
Directions
- Rinse the short-grain rice in cold water 3 to 4 times until the water runs nearly clear, then drain and let rest in a sieve for 10 minutes. Combine the rice, 2 1/4 cups cold water, and salt in a rice cooker and cook according to manufacturer directions, or simmer covered on the stovetop for 18 minutes then rest 10 minutes off heat.
- While the rice cooks, prep your toppings: thinly slice the scallions, shred the nori sheet into 1-inch strips with kitchen shears, and separate the egg yolks from the whites, reserving yolks in small individual cups.
- Open each natto package and pour off the small liquid sachet (or reserve it for soups). Transfer the beans to a small bowl, add 1/2 teaspoon of the included tare sauce, and stir vigorously with chopsticks for about 1 minute until the natto becomes glossy and develops long sticky strings; this aeration is key to the proper texture.
- Divide the hot steamed rice among four warm donburi bowls, fluffing gently with a rice paddle to keep the grains separate and glossy.
- Spoon a generous mound of the whipped natto over the center of each rice bowl, then drizzle 1 teaspoon soy sauce and 1/2 teaspoon sesame oil around the edges of the rice.
- Garnish each bowl with a spoonful of karashi mustard placed beside the natto, a sprinkle of sliced scallions, shredded nori, and a scattering of toasted sesame seeds. If using, carefully tip one raw egg yolk over the top of the natto so it nestles in without breaking.
- Serve immediately while the rice is still steaming hot. Instruct diners to stir everything together vigorously before eating so the natto strings, yolk, and sauces coat every grain of rice; eat with chopsticks and pair with hot green tea or miso soup.
Cook’s Notes
- Always stir natto vigorously for at least 60 seconds before serving; this develops the signature sticky, stringy texture that defines the dish and improves flavor release.
- If you cannot find karashi mustard, mix 1 part English or Chinese mustard with 1 part water and a pinch of sugar for a workable substitute; wasabi paste also adds a comparable sharp heat.
- For the best eating experience, use freshly cooked steaming hot rice so the natto warms slightly and the optional egg yolk gently cooks at the edges when stirred in.
- Skip the raw egg for young children, pregnant women, or anyone with compromised immunity; a soft-boiled egg or a teaspoon of mayonnaise stirred into the natto is a safe, creamy alternative.
- Stir-fry leftover natto with kimchi and pork for a quick banchan-style side dish, or blend a package into miso soup just before serving for an extra umami boost.
