Salmon and crème fraîche shots topped with watercress purée and pickled cucumber

Preheat the oven to 180°C/gas mark 4

To begin, take your salmon fillets and lay them on some foil, approximately 25cm square. Drizzle with some of the olive oil and season liberally with the salt and pepper then place a few lemon slices on top

Wrap the foil around the fish to create a bag that is sealed at the edges and place in the oven for 12–15 minutes, or until the salmon is just cooked through

Take out the salmon and leave it to cool, then flake into a bowl using a fork. Mix in 100g of the crème fraîche and stir in the dill. Finely chop half of the pickled cucumber and add to the bowl, along with a dash of lemon juice and salt and pepper to taste. Cover and refrigerate for 1 hour

For the watercress purée, bring a saucepan of salted water to the boil and add the watercress. Cover and bring to the boil again (this should take about 1 minute maximum) then drain and plunge the leaves into a bowl of iced water

Drain the watercress again, reserving just a couple of tablespoons of the water, then place in a blender and blitz to a purée. Use the leftover water to thin the purée if necessary and season with salt and pepper

To serve, divide the salmon between glasses then top with a layer of the watercress purée. Finish by dotting some of the remaining crème fraîche in the centre and add half a slice of pickled cucumber to each glass
