Method

1
Remove the mackerel head and fillet the fish. Slice along the pin bones and remove all bones in one action.

  • 30g of salt
  • 30g of sugar
  • 4 pinches of coriander seeds
  • 2 limes
2
Freeze the bag after which the paste can be cut into rectangles. Place the rectangles into a dehydrator for four hours at 57˚C until dry
3
After one hour remove and wash the fillets. Dust lightly with transglutaminase on flesh side only and roll both fillets together, flesh sides touching, into a cylinder shape wrapping in cling film. Blanch in boiling water for 45 seconds, plunge into ice cold water and refrigerate

Place all the seaweed cracker ingredients into a food processor and blitz into a paste. Place the paste into a vacuum packing back unsealed and use a rolling pin to flatten into a sheet a few millimetres thick
  • 90g of scallops
  • 60g of tapioca starch
  • 30ml of water
  • 1/2 sheet of nori seaweed

  • 75ml of lemon juice
  • 1 pinch of salt
6
Take the egg yolks and place into a vacuum pack bag, seal and place into the water bath for 50 minutes at 65˚C. Remove from the bath and pass the mixture into a piping bag (to prevent the egg from forming a skin). Leave the bag at room temperature

Peel and deseed the cucumber. Cut the flesh into small cubes, sprinkle with sea salt and freeze on a cling filmed tray for one hour. At this point the cells of the cucumber will have broken down. Rinse under cold water and refrigerate
