Add the marinated prawns to this mixture(you can use the leftover masala from the bowl by adding a couple of tablespoons of water. Never add water to cook the prawns).
8)Now add the softened kudam puli and cook covered, in medium heat, until the prawns changes its color and is almost cooked.
Once the prawns are almost cooked, remove the lid and roast them in low flame for 10-15 minutes, until it reaches a brown color and fully dried up. Add salt, if needed.
Before turning off the stove, make a small clearing in the centre of the cooked dish and add 1 tbsp coconut oil and a sprig of curry leaves. When u get a beautiful aroma, mix the entire dish and keep it slightly closed so as not to form any condensation inside but at the same time stopping the aroma to escape from the dish completely.
11)Serve with steaming rice or chappathi.
