Step 1

Heat oven to 200C/180C fan/gas In a small bowl, mash the butter with the tarragon, crabmeat and zest, and season. Make a few deep slashes across the fillets on both sides of the sole, then place the fish, dark-skin up, in a large roasting tin. Season, then stuff the crab butter into the cuts, spreading any remaining butter on top. Lay a few lemon slices over the fish, then pour over the wine.

Step 2

Bake for 15-20 mins, depending on the size of the fish – the flesh should flake away easily from the bone when gently pushed with a knife.

Step 3

Carefully remove the fish from the tin, place on a warm plate or platter and cover with foil while you make the sauce. Set the tin over a low heat, add 2 tbsp water and bring to the boil. Let the sauce bubble for a few mins, then stir in the capers and cream. Pour the sauce over the fish and serve with steamed potatoes and a green salad.
