- Grind the coconut along with 1/8 tsp mustard seeds, 1/8 tsp cumin seeds and 1/4 cup yoghurt to a fine paste. Set aside. Deep-fry the bitter gourd slices and green chilies stirring occasionally until browned, about 10 – 15 minutes over medium-high heat. Remove to a paper towel. Transfer the fried bitter gourd into a bowl and crush slightly. Add the ground paste, little salt, 3/4 cup yoghurt and mix well. Taste-check for salt. Heat coconut oil in a small pan. Splutter mustard seeds and fry dry red chilly and curry leaves. Pour over the bitter gourd mixture. Mix well. Serve with rice.
