^^^ That, or if you want a 'healthy' option, pan-fried fillets with the pan 'de-glazed' afterwards with a mixture of orange & lemon juice, parsley and capers, served with some sweet potato wedges and broccoli!
For whole fish. Stuff it with a couple of bits of lemon sliced and halved anda couple of sprigs of dill. Wrap in foil and bake at 200c for about halfan hour.
Depends where they are from - if any risk of earthiness, I smoke 'em, cold or hot. Otherwise, bake in foil, slash and grill or fillet, roll in seasoned flour and fry. Baked or grilled, they get butter and lime/ginger/chilli/garlic/coriander or lemon/bay/thyme or lemon/dill
