- Making Lauki Curry: Rinse and peel the lauki and cut into small bite size pieces. Add the lauki pieces, salt, yogurt , curry leaves, green chilies and water in a pan. You can even mix the curd with water first very well and then add lauki, salt, curry leaves and green chilies. Stir and cook for 12 to 15 minutes till the lauki is cooked without a lid. Add the coconut milk and simmer for a minute. Don't cook much as the coconut milk would otherwise curdle. For Tempering Lauki Curry: Heat oil in a small pan. Add the mustard seeds and allow them to crackle. Add the cumin and fry for some seconds. Pour this tempering along with the oil on the curry. Stir and serve the bottle gourd curry hot with steamed rice.
