You will also need a grill pan, lined with foil and smeared with a trace of butter.

1. Begin by wiping the fish fillets with kitchen paper to get them as dry as possible, then place them in the foil-lined grill pan.
2. Season with salt and pepper, then spread the Coriander and Lime Tartare Sauce all over the surface of the fish.
3. Now, in a bowl, mix the breadcrumbs, cheese, coriander, cayenne and lime zest together, then sprinkle this over the fish as evenly as possible.
4. Dot with a little butter. Place the grill pan as far from the heat as possible and grill the fish for 10-15 minutes, depending on its thickness – it should be just cooked through and the top should be crispy and golden.
5. Serve with tiny new potatoes, tossed in chives and lemon juice, and a plain lettuce salad.
