Method:

Cut off the top of the green coconut. Scoop out the pulp and take out all its water. Boil the headless prawns and keep aside. Heat the oil in a wok; sauté the onion paste. Add ginger-garlic-green chilli paste, red chilli powder, sugar, and salt. Add some of the coconut pulp and water to the mixture. Add the boiled prawns and cook for 3 minutes. Put this mixture back into the coconut shell, replace the coconut top. Seal with wet dough and bake in the oven for 5 minutes. Serve the dish after removing the coconut top.
