Method
- Steep the kombu in the cold water 30 min, then bring slowly to 60C and hold 20 min. Do not let it boil. 30 min
- Lift the kombu out the moment small bubbles climb the pan.
- Raise to 80C, add the katsuobushi all at once, and take off the heat immediately.
- Let the flakes sink, about 2 min, then strain through muslin without pressing. 2 min
How to tell it is going right
This dish has no standard of its own yet. It is judged on the techniques it exercises: checked at the pan, while there is still something to be done about it.
Dashi 29 recipes
- It is clear enough to read the bottom of the pan through it. Cloudiness means it boiled, or the kombu stayed in past the first small bubbles, and neither can be strained out afterwards.
- Pale gold rather than brown, nearer the colour of weak tea. A brown dashi has been cooked too hard or too long and will taste of the pan rather than of the sea.
- The kombu came out before the water reached a simmer, and it is supple rather than slimy. A slippery surface on the sheet means alginates have started to leach, and the broth will feel viscous on the tongue.
- Strained without pressing. Squeezing the flakes or the kelp forces out bitterness and fine particles, and the difference is obvious in the finished bowl.
- Tasted alone it is savoury and faintly sweet with no fishiness and no bitter edge. Fishy means the katsuobushi steeped rather than settling; bitter means heat.
Where it goes wrong Heat, or time, or both. Kombu boiled gives up alginates and turns the broth slippery and faintly bitter; katsuobushi left to steep turns it sour and fishy. Almost every dashi failure is an excess of one of the two things the cook controls, and neither is recoverable once it has happened.
Straining & passing through a sieve 148 recipes
- Nothing solid got through: a finger drawn through what came out finds no fibre, seed, skin, curd, or grit.
- Where the dish wants body it was worked through rather than left to drip, and the solids left in the mesh are spent and dry rather than still holding liquid worth having.
- It is judged on the tongue rather than by eye: smooth, with no residual grain left behind after the mouthful has gone.
- The mesh was fine enough for the job and held its shape, and nothing bypassed it by going over the rim.
- The yield is close to what went in less the spent solids: not half of it abandoned in the sieve because it stopped running and nobody pushed.
Where it goes wrong It was pushed through a mesh too coarse for it, or the sieve was overloaded and slopped at the rim, so the fibres it was meant to remove are in the finished sauce and it reads grainy on the tongue.

Umami bridges best with umami: sake’s amino depth shakes hands with dashi and soy where tannic wine would argue.
