Place the prawns in a large bowl and add all the marinade ingredients. Mix well and leave in the refrigerator for a couple of hours or overnight.
Tomato and pepper sauce:
Liquidise the onion and the tomatoes until well blended. Heat the oil and the butter in a deep frying pan. Add the curry leaves and fry for 4–5 minutes. Add the tomato mixture to the pan and cook for 5–7 minutes, stirring until the liquid from the tomatoes has evaporated.
Add the peppers and the fish seasoning, and cook for 3 minutes. Add the prawns and mix well. Cook over medium heat for 5–7 minutes or until the prawns are pink in colour and the sauce has thickened. Serve with bread, onion salad and roasted vegetables.
