|Lemon juice||4 Tablespoon|
|Chilli powder||1 Teaspoon|
|Garlic||1 Clove (5 gm), crushed|
|Brown sugar||1 Teaspoon (heaped teaspoon)|
|Vegetable oil||3 Teaspoon|
|Chopped cilantro||2 Teaspoon (chopped freshly)|
Make a slit down the back of each prawn and open out into butterflies.
In a bowl, mix together the remaining ingredients until well blended. Add the prawn, turn to coat well then leave to marinate for 1 hour.
Preheat the grill to hot.
Transfer the prawns together with their marinade, to a shallow ovenproof dish large enough to take them in one layer. Grill for 10-15 minutes, turning and basting several times during the cooking. Serve immediately.
