Octopus, lobster and scallop wontons with cherries and pink fir potatoes

Preheat a water bath to 72°C

Begin by preparing the octopus. Cut the tentacles just below the eyes and trim the web between the tentacles, leaving you with 8 individual tentacles. Retain the head for the sauce and generously salt the tentacles, washing them thoroughly in salt water until clean. Leave to drain on a towel until dry

Transfer the octopus to a vacuum bag and add the chicken stock, thyme and bay leaves. Cook in a water bath for 5 hours

Meanwhile, prepare the filling for the wontons. Bring a large pan of salted water to the boil and cook the lobster for 2 minutes, refreshing immediately in iced water. Once cold remove the meat from the lobster and dice it into 0.5cm pieces, reserving the shell for the sauce

Blend the scallops in a food processor until smooth, then add the cream in small batches until fully incorporated. Season with salt and fold through the lobster pieces. Put the mixture into a piping bag and reserve in the fridge. This mixture will make more than 8 wontons, but any leftovers can be frozen

Remove the cooked octopus from the bag, reserving the juices to make the sauce. Dry the octopus on a kitchen towel and, using the towel, carefully rub away the membrane and the suckers along the tentacle leaving a smooth piece of octopus. Set aside, ready to reheat before serving

To make the sauce, chop the octopus head and blitz the lobster shell in a food processor until both are in very small pieces. Heat a saucepan over a high heat with a little oil and fry both until caramelised and golden, then deglaze the pan with the brandy and reduce by ¾

Add the octopus juices to the pan, stir well and cook for 30 minutes. Strain the mixture through a sieve, then return to the pan and reduce to a thick sauce consistency

To make the wontons, pipe a small amount of the scallop and lobster mix into the center of a wonton wrapper and moisten the edges with a little water. Fold the wrapper from one corner to the opposite to form a triangle and seal the edges, pushing out any air as you go. Pick up the wonton and fold the left point around the right point to form a tortellini shape. Repeat this process to make 8 wontons in total. Leave to air dry for around 20 minutes

For the pink fir potatoes, boil the potatoes in salted boiling water until tender. Meanwhile, heat the butter in a small saucepan until browned, leave to cool slightly and transfer to a blender with the nori seaweed. Blend the butter and nori until smooth and, once the potatoes have cooked, transfer both to a vacuum bag. The potatoes can be reheated in the bag just before serving

Place the cherries in a small pan and cover with the white balsamic vinegar. Just before serving warm the cherries very gently

Ahead of serving gently reheat the seafood sauce in a pan. Add the octopus tentacles to the pan and reheat in the sauce until warmed through. Meanwhile, deep fry the wontons at 180°C for 1-2 minutes until golden brown and crispy

To serve, remove the potatoes from the bag and place one on each plate. Arrange two pieces of octopus on each plate followed by two wontons and three warm cherries. Drizzle over the sauce and rapeseed oil, then garnish with oyster leaves and samphire. To finish, put the yuzu juice into an atomiser and spray over the plated dish
