Serves 4300 minMedium

Ingredients

  • 1 saba mackerel fillet, pin-boned
  • 2 tbsp salt for curing
  • 100ml rice vinegar for curing
  • 400g cooked sushi rice, seasoned with vinegar, sugar, salt
  • 1 sheet kombu, 20x10cm
  • Gari (pickled ginger) to serve

Method

  1. Salt the mackerel fillet and leave for 30 minutes; rinse and pat dry.
  2. Submerge in rice vinegar for 20 minutes; the flesh will turn opaque.
  3. Line a battera mould or small loaf tin with cling film.
  4. Lay the mackerel skin-side down in the mould, then place kombu on top.
  5. Press seasoned sushi rice firmly over the kombu in an even layer.
  6. Cover with the lid or a weighted board and refrigerate for 4-6 hours.
  7. Remove from mould, slice into 8 triangular pieces, and serve with gari.

Editor tip. The pressing mould can be improvised with a loaf tin and a weighted board; the flavour improves after 4-6 hours of pressing in the refrigerator.
