What is nimono in Japanese cooking?

Nimono is a category of Japanese simmered or braised dishes cooked in seasoned dashi broth. The word comes from niru (to simmer) and mono (thing). Ingredients are gently cooked in a broth of dashi, mirin, sake, and soy sauce until they absorb the liquid's umami depth while retaining their natural texture and shape.

What is dashi and why is it used in braising?

Dashi is a Japanese stock made by briefly steeping kombu (dried kelp) and katsuobushi (dried bonito flakes) in hot water. It is the backbone of nimono braising because it provides a clean, layered umami base — glutamate from the kombu, inosinate from the bonito — that penetrates the ingredient during the braise without the heaviness of meat-based stocks.

What vegetables work best for nimono?

Root vegetables with dense texture — daikon, taro, lotus root, carrot, burdock — absorb dashi broth most effectively and hold their shape through long simmering. Tofu, konnyaku, and aburaage (fried tofu) are also classic nimono ingredients. Delicate vegetables like spinach or watercress are better as garnishes added at the end, not braised through.

What is the difference between nimono and Western braising?

Western braising typically uses a meat-based stock, wine, or tomato — heavy, rich braising liquids that reduce into thick sauces. Nimono uses light, clear dashi broth, allowing the ingredient's own flavour to remain the focus. The broth is subtly sweet, savoury, and clean — a vehicle for umami absorption, not a sauce to be poured over.

Can nimono be combined with grilling?

Yes — and this combination is one of the most powerful techniques in the Soil kitchen. Braising first saturates the ingredient with umami depth and ensures even, tender cooking throughout. A brief finish over binchotan or under a grill then creates a caramelised surface and smokiness that contrasts with the silky interior. The two techniques answer different questions — and together they answer everything.

How do you make a simple nimono dashi broth?

Combine 600ml ichiban dashi with 3 tbsp mirin, 2 tbsp sake, 1.5 tbsp light soy sauce, and a pinch of salt. Bring to a simmer, add your prepared vegetables, cover with an otoshibuta (drop lid) or cartouche, and simmer gently at 85–90°C until the ingredient is completely tender and has absorbed the broth's colour. Cool in the broth for maximum flavour penetration.

What is an otoshibuta and why is it used?

An otoshibuta is a drop lid — a lid placed directly on top of the simmering ingredients rather than on the rim of the pot. It keeps ingredients submerged in the broth, ensures even heat distribution across the surface, and reduces evaporation while still allowing gentle circulation. A cartouche (circle of parchment paper) achieves the same effect in Western kitchens.
