handful of coriander, chopped, plus extra to garnish
1 tablespoon vegetable oil, plus extra for oiling
4 medium mackerel, scaled and gutted
salt and pepper
Mix together the lemon rind and juice, chilli, coriander and oil. Using a sharp knife, make 3 shallow slashes across either side of each fish. Season and rub all over with the lemon mixture.
Place the fish in a lightly oiled grill pan and cook under a preheated hot grill for about 7 minutes. Turn over and cook for a further 5 minutes, or until the fish is just cooked through. Scatter over chopped coriander and serve with lemon wedges, chapatis and a tomato salad.
