Cured salmon with pickled cucumber salad, apple gel, purslane and horseradish mousse

Begin preparing the salmon a day in advance. Mix together all the ingredients (apart from the salmon), ensuring they are well combined by rubbing the mixture between your hands

Sprinkle half the mixture onto a tray large enough to hold the salmon. Lay the fish on top, then add the remaining curing mixture on top, ensuring it is thoroughly coated. Tightly wrap the tray in cling film, then set aside at room temperature for 90 minutes

While you wait, begin preparing the horseradish cream. Grate the fresh horseradish, cucumber and apples into a bowl, then add the rest of the ingredients and stir to combine. Cover and leave to infuse in the fridge overnight

You can also make the apple gel the day before. Warm the apple juice in a pan and mix together the agar agar and sugar. Whisk the agar mixture into the warm apple juice, then bring the mixture to the boil and simmer for 1 minute, whisking constantly. Allow to cool, then blitz in a blender to make a fluid gel. Transfer to a squeezy bottle and reserve in the fridge

After 90 minutes, flip the fish over, working the now wet mixture into the fish, then cover in cling film again and leave for another 90 minutes

Quickly but thoroughly rinse the curing mixture off the fish, then pat dry and leave in the fridge uncovered overnight to dry out and set firm

The next day, make the salad. Bring the water, sugar and vinegar to the boil, then set aside to cool slightly. Meanwhile, sprinkle the diced cucumber with salt and leave to drain in a colander for 15 minutes 

When the pickle liquor has cooled slightly (but is still warm), add the mustard seeds and leave for 10 minutes. After this time, add the cucumber to the liquor and bring back to the boil. As soon as it is boiling, remove from the heat, add the honey and capers, then leave to cool completely

While you wait, strain the horseradish cream mixture through a fine sieve into a bowl. Use an electric whisk to whisk the cream to soft peaks, then season to taste. Transfer to a piping bag

Once the pickled cucumber has cooled, strain off the liquor and mix the cucumber with the diced apple, dill and shallots. Dress to taste with the Chardonnay vinegar and olive oil, then set aside

When ready to serve, slice the cured salmon into thick strips on a 45-degree angle. You should get 15-20 slices

To serve, place a slice of salmon to the left of each serving plate. Spoon over some trout roe and add a few fronds of dill. Squeeze a large dot of apple gel next to it and dust it with the blitzed nori powder. Add a small pile of the cucumber salad, then garnish it with purslane leaves. Finally, pipe a dot of the horseradish cream and garnish with a sprig of bronze fennel
