Mackerel miso soup

A store-cupboard supper that is much more interesting than the norm...

This is inspired by a game-changing soup I once ate at a chef’s residency in London. David Chang (founder of the New York restaurant group Momofuku) was cooking at the St John Hotel for a week and his menu included a miso soup made from a broth infused with smoked eel bones. I make it with either smoked eel or smoked mackerel and it has become something of a store-cupboard supper.

A note on dashi

Dashi is a simple stock made using dried bonito flakes and kelp, sometimes with the addition of mushrooms. The good news is that most people in Japan do not make it themselves – sachets of instant dashi are as common there as stock cubes are here (and much better). I buy mine through souschef.co.uk. Waitrose also sells ready-to-use liquid dashi in plastic pouches.

Ingredients

Ingredients

2-4 sachets instant dashi (according to your preference) dissolved in 1 litre water
4tbsp miso paste
1 fillet smoked mackerel or smoked eel, cut into small pieces
150g tofu, cut into small cubes
2 large pinches dried wakame seaweed (optional), soaked in cold water as per packet instructions and drained
2 spring onions, finely sliced
  1. Method

    Step 1

    Bring the dashi to a simmer. Put the miso in a small bowl and thin it using 1tbsp of the broth to help it disperse more easily. Then stir this mixture into the remaining dashi.

    Step 2

    To serve, put the smoked mackerel or smoked eel in the bottom of the bowls with the tofu and wakame, and pour over the broth. Top with the sliced spring onions.
