Total Time:PREP 30 mins to 1 hour COOK No cooking required

Ingredients -

1 tsp rapeseed oil, for greasing
1 large cucumber, peeled and very finely sliced
400g/14oz smoked salmon fillet (unsliced), chopped
1 lemon, juice only, plus extra lemon wedges to serve
200g/7oz full-fat cream cheese
450ml/16fl oz double cream
300g/10½oz cooked tiger prawns, shells removed, de-veined, plus 6 extra tiger prawns, shells left on
50g/1¾oz watercress leaves
Melba toast, cut into quarters, to serve
sea salt and freshly ground black pepper

Directions -

Grease a 22cm/9in savarin mould with a little rapeseed oil, then line it with cling film, making sure the cling firm overlaps the edges of the mould all the way around.

Arrange three-quarters of the cucumber slices in overlapping layers to cover all of the inside of the mould (the effect should resemble fish scales). Set aside.

Blend the chopped smoked salmon with the lemon juice in a food processor until smooth. Add the cream cheese and blend once more to combine.

With the motor still running, gradually pour in the double cream until the mixture thickens to a mousse, scraping the sides of the food processor with a spatula halfway through blending. Season, to taste, with salt and freshly ground black pepper, and more lemon juice if desired.

Carefully spoon the mousse into a piping bag, then pipe half of it into the bottom of the cucumber-lined mould. Arrange a layer of prawns all over the surface of the mousse, then pipe over the remaining mousse and smooth the top using a palette knife. Arrange the remaining cucumber slices on top, then cover with cling film and chill in the fridge for at least 30 minutes, or until ready to serve.

To serve, peel away the cling film, then invert the savarin mould onto a serving plate. Gently lift away the mould and peel off the cling film that was lining the mould. Pile the watercress into the centre of the ring of mousse and top the watercress with the extra tiger prawns. Serve the mousse in slices with lemon wedges and Melba toast.
