  • 4 mackerel fillets, pin boned
  • 3 small sheets nori
  • 50g sea salt flakes
  • 25g caster sugar
  • 20g chia seeds
  • 200ml   apple juice
  • ½ tsp spirulina
  • 50ml lemon juice, plus a little for seasoning
  • 10g white or regular soy sauce or wakame seaweed
  • for deep frying oil
  • sprigs to serve dill


  • 2 small cucumbers
  • 50ml white vinegar
  • 30g caster sugar
  • 10g salt


  • STEP 1

    Cut the mackerel fillets, lengthways, from the head end to the tail so you’re left with 1 silver belly fillet and 1 striped topside fillet from each. Put the nori in a food processor and blend until you have a fine powder, then add the sea salt and sugar and blend again. Lay the fish flesh-side up on a tray and sprinkle over the nori salt. Leave it for 7 minutes and then rinse the fillets, drain and chill skin-side up on a lightly oiled baking tray.

  • STEP 2

    Mix the chia seeds with 100ml apple juice and stir in the spirulina. Leave until the liquid is absorbed and then stir in more juice, a little at a time, letting each amount be absorbed and making sure there are no lumps. Once the seeds have swollen and are soft, season the mixture with lemon juice and soy.

  • STEP 3

    Peel the cucumbers and cut one into ½ cm thick slices, and the other into long thin batons. Put the remaining ingredients in a pan with 400ml water and bring to the boil. Add the cucumbers and cool.

  • STEP 4

    Heat a pan with some oil in it (no more than 1/3 full) until it is 170C. Fry the wakame until it starts to pop and expand, about 10-20 seconds, then scoop it out and drain it on kitchen paper.

  • STEP 5

    Blowtorch the fillets all over using a fierce flame, till they start to bubble and get black spots on the skin, or use a very hot grill to blister the skins. The fish should be just cooked. Mix the soy and lemon juice and sprinkle it over. Blowtorch the cucumber strips.

  • STEP 6

    To serve, spoon the chia seeds into 4 shallow bowls, add 2 discs and a strip of cucumber to each and add some dill. Add a belly and top fillet to each dish and sprinkle over the fried wakame.
