Instructions
- 1
Pat the trout fillets thoroughly dry with paper towels to ensure crispy skin.
- 2
Season both sides of each fillet with sea salt and black pepper.
- 3
Heat the rapeseed oil and 15g of butter in a large frying pan over medium-high heat.
- 4
Place the trout fillets into the pan skin-side down, pressing gently for ten seconds.
- 5
Cook undisturbed for three to four minutes until the skin is golden and crisp.
- 6
Turn the fillets carefully with a fish slice and cook for one to two minutes until just opaque.
- 7
Transfer the cooked fillets onto warm plates and keep warm.
- 8
Melt the remaining butter in the residual pan heat over low hob heat.
- 9
Add the chopped shallot and cook for one minute until soft and translucent.
- 10
Stir in the capers, lemon zest, and lemon juice until the butter sauce emulsifies.
- 11
Add half of the watercress to the pan for thirty seconds until lightly wilted.
- 12
Spoon the warm lemon sauce and watercress over the trout, garnishing with the remaining fresh watercress.
Chef's tips
Drying the fish skin completely is essential for achieving a crisp texture without sticking. Avoid moving the fillets during the initial skin-side fry to allow a solid crust to form. Work quickly when making the butter sauce so the fresh watercress retains its vibrant green colour.
Ingredient substitutions
- Test Valley trout fillets โ rainbow trout fillets or Arctic char
- rapeseed oil โ sunflower oil
- unsalted butter โ plant-based block butter
Storage
Best enjoyed immediately, but leftovers can be kept in an airtight container in the fridge for up to one day.
Reheating
Warm gently in a low fan oven at 140ยฐC covered loosely in foil for six to eight minutes.
Common mistakes to avoid
- โขAdding wet fish to the pan which steams the skin instead of crisping it
- โขOvercooking the trout which dries out its delicate chalk-stream flesh
- โขAllowing the butter sauce to burn by using high heat instead of gentle residual heat
