Mix the ginger-garlic paste, turmeric powder, salt, and 1 tablespoon of the red chilli powder. Apply on chicken and set aside while you prepare the spice paste and curry. For the spice paste, heat the cast iron skillet until it's smoking. Turn the heat down. Except for the coconut and water, toast all the ingredients until they release their aroma, about 15 seconds, stirring constantly so they don't burn. Set aside to cool.

Once cool, blend with the coconut and 3 tablespoons water till it forms a paste. mix everything and mix. cook for few mins and serve hot.
