1. Marinate prawns with ingredients 2 to 6. If you want the prawns to stay uncurled after cooking, pass a bamboo skewer or broom stick through the prawns (But don't forget to remove the sticks from the cooked prawns before eating). Keep it marinated for 8-24 hrs in the refrigerator.
2. Grind ingredients 7 to 13 to a thick paste.
3. Heat oil in a shallow pan. Roast the marinated prawns till they cook. Drain and keep aside.
4. In the same oil, roast the ground masala till oil leaves the sides and raw smell disappears. Add salt to taste, the marinade and the cooked prawns. Mix well and keep for 2-3 mins on slow fire. Add ghee, mix and cover. When the masala gets thick, transfer to serving dish, garnish with chopped coriander leaves and serve hot with lemon wedges.

Same masala could be used for making Ghee Roast of 1.5kg Chicken.
