800 g (about 1 lb 10 oz) salmon, skinned and boned
180 ml (¾ cup) dry white wine
60 ml (¼ cup) water
1 carrot, sliced
1 leek, white part only, sliced
1 tender celery stalk, finely sliced
1 bay leaf
2-3 lemon slices
Salt and 5-6 peppercorns
Sauce:
2 tbsp butter
5 tbsp cornflour
500 ml (2 cups) or more hot milk
½ large onion
1 bay leaf
Salt and pepper to taste
5 sheets gelatine steeped in iced water for 5-7 minutes
125 ml (½ cup) low fat mayonnaise
2 tbsp lemon juice
2 tbsp chopped dill
1-2 spring onions, very finely chopped
1-2 tsp Dijon mustard
250 ml (1 cup) full cream whipped to soft peaks
Salt and pepper to taste
Pour the wine and water in a shallow saucepan and add the
onion, sliced vegetables, peppercorns salt, bay leaf and simmer for about 7
minutes. Place the salmon in the stock,
spoon a few vegetables and the lemon slices on top. Cover the saucepan, and poach for 7 minutes,
then turn the fish over and simmer for 8 minutes more or until the fish flakes
easily. Remove the salmon and cool.
Reduce the cooking liquid to 2-3 soupspoons, strain and reserve.
In the meantime,
bring the milk to the boil, with the onion and bay leaf. Remove from the heat and leave to infuse for
at least 10 minutes. To prepare the
sauce, melt the butter add the cornflour and cook, stirring for 2-3 minutes.
Strain the milk and add it gradually to the roux, stirring constantly. Simmer
the sauce until it thickens, stirring, and cook for 3-4 minutes more. Remove
from the heat and cool for 1 minute. Squeeze the gelatine sheets and mix very
well into the warm sauce, until completely combined.
Add the sauce and the reserved cooking liquid to the poached
salmon and blend until the mixture is quite smooth. Transfer the mixture onto a large bowl, add
the mayonnaise, lemon juice, mustard, chopped dill, spring onions and mix well
together. Fold in the whipped cream and
then taste for seasoning and adjust accordingly. Finally, spoon the mixture into a souffle
dish lined with cling film, cover and refrigerate for at least 8 hours or
overnight.
One hour or more before serving, invert the salmon mousse on
a serving dish and garnish with halved lemon slices, smoked salmon roses and
parsley twigs.
