Superlative fish with a delicate sauce
With its blushing coral flesh and superlative flavour, the sea trout is closer to the rare wild salmon than it is to its river-dwelling relatives. It is only available for the few short months a year when it returns to our rivers to spawn. Keep things simple by pairing it with a delicate, and very British, watercress sauce.
1 small onion, halved
1 tbsp peppercorns
1 bay leaf
3 sprigs of thyme
100ml white wine
1 tbsp salt
4 sea trout fillets, pin boned
For the sauce:
A medium bunch of mint
2 tbsp capers, rinsed if packed in salt
200ml creme fraiche
Zest of 1 unwaxed lemon
Put all the trout ingredients in a saucepan large enough to hold the fish and just enough water to cover by about 2cm. Lift the fish out and set aside, then bring the pan to the boil and simmer for 15 mins. Add the fish and cook for 5 mins, then turn off the heat and leave for another 3-5 mins, depending on thickness, until it comes apart in flakes. Lift out and plate.
While the fish is cooking, make the sauce. Pick the mint leaves and roughly chop the watercress, discarding any particularly tough stalks. Put in a food processor with the capers and whizz until roughly chopped.
Tip into a small pan and add the creme fraiche. Heat until warm, then add the zest of the lemon and a grating of nutmeg. Season to taste. Serve on top of the fish.
