Quick Miso Soup
A warm, savoury bowl of miso soup with tofu and seaweed, ready in 10 minutes. The easiest way to start a Japanese-style meal. In Japan it turns up at breakfast as often as at dinner, always alongside rice, and every household makes it a little differently. The one rule everyone agrees on is that the miso goes in at the very end, with the heat off.

Ingredients
- 4 cups water
- 2 tsp dashi powder (or 1 stock cube)
- 3 tbsp miso paste
- 150g soft tofu, cubed
- 2 tbsp dried wakame seaweed
- 2 spring onions, sliced
Instructions
- 1Put the water in a saucepan over medium heat and bring it to a gentle simmer — small bubbles around the edge of the pan, not a rolling boil.
- 2Stir in the dashi powder and let it dissolve completely, about 30 seconds, before anything else goes in.
- 3Add the tofu cubes and the wakame and simmer for 2 minutes, just long enough to warm the tofu through and rehydrate the seaweed.
- 4Take the pan off the heat and let it settle for a moment, until the surface stops moving.
- 5Set a small sieve over the pan, put the miso in it, and press it through with the back of a spoon. Alternatively, whisk the miso smooth in a ladleful of the hot broth before adding it back.
- 6Stir the dissolved miso into the soup gently. From this point on it must not boil — heat above roughly 80°C drives off the aroma that makes miso worth using.
- 7Taste and adjust: if the soup tastes flat, stir in a little more miso; if it is too strong, loosen it with hot water.
- 8Ladle into bowls, top with the spring onions and drink it while it is hot.
Tips
- Never boil the miso, or it loses its flavour and aroma.
- White miso is milder; red miso is stronger — pick whichever you like.
- Dashi powder keeps the soup quick; you can also use a stock cube.
- Press the miso through a fine sieve instead of dropping the paste straight into the pan. It dissolves evenly and leaves no lumps sitting at the bottom of the bowl.
- Lower the tofu in with a spoon rather than tipping it from the bowl. Soft tofu breaks up at the slightest knock and a cloudy soup looks unappetising.
