Wash fish chops and pat dry. Squeeze the lemon, set aside 1 teaspoon of the juice. Mix the rest with basil and some pepper. Peel the garlic clove, chop finely and add to the lemon-basil mixture. Fold in the oil vigorously.
Spread the marinade on both sides of the cod chops, cover and leave to stand for 30 minutes. Mix butter with the remaining lemon juice. Crush green pepper a little. Chop the herbs (keep some dill for garnishing) and mix them with the pepper into the butter. Season to taste with salt and pepper. Form the butter mixture into a square in aluminium foil, then place in the fridge. Dab fish chops dry and grill under the hot grill for 4-5 minutes on each side. Cut the herb butter into slices with a waistband knife and arrange on the chops. Garnish with dill and lime slices.
