you can use coconut milk or grated coconut or paste to the curry. If using grated coconut or paste add it just before adding green gram and fry for about 2 to 3 minutes. If using coconut milk, add ¼ cup water to the curry to cook, once the gram is cooked fully, pour ¼ cup coconut milk and allow it to bubble. Do not overcook. Switch off the stove.
