Dill and vodka cured Fjord Trout with Bloody Mary sorbet and avocado

To begin, cure the trout. Toast the black pepper and coriander seeds in a hot dry pan until aromatic. Place the remaining dry ingredients and toasted spices in a food processor and blend to form a coarse powder

Add the vodka to the mixture and spread over the trout, including the underside. Leave to cure for 24 hours, turning every 8 hours

On the same day as you cure the trout, make the dill oil. Blanch the dill in a pan of salted boiling water for 1 minute. Refresh in iced water before squeezing out as much liquid as possible

Transfer to a liquidiser with the oil and blitz until smooth, then place in a cheesecloth and hang overnight in the fridge with a jug positioned below to collect the oil that drips through. Store the resulting oil in a bottle until ready to serve

To make the Bloody Mary sorbet, add all of the ingredients to a pan and warm gently. Taste the mixture and adjust the seasoning if necessary

Chill before churning in an ice cream maker until frozen. Transfer to a container and freeze to firm up before serving

Preheat the oven to 150°C/gas mark 2

Slice the sourdough very thinly using a good bread knife or meat slicer. Rub with oil and salt and bake in the oven for 15–20 minutes until crispy. Break up some of the croutons into a crumb to sit the sorbet on when plating and leave the remaining whole for garnish

When the trout is ready to serve, wash the fillet in cold water for at least 5 minutes to remove any the excess cure and dry with kitchen paper. Cut into 1cm cubes

To make the avocado purée, destone the avocados and place the flesh in a liquidiser with the lime juice, salt and pepper. Blend until silky smooth and transfer to a squeezy bottle

To plate the dish, dot cubes of trout all around the plate, interspersed with dots of avocado purée. Add a mound of sourdough crumb, followed by a quenelle of the Bloody Mary sorbet. Add drops of dill oil, shards of sourdough croutons and finish with the dill tops and nasturtium leaves
