Wash and soak the beans overnight in plenty of water. Next morning, drain all the water and rinse beans until the water runs clear. Wash and drain the rice and keep aside. Meanwhile bring 3 cups of water to a boil. Heat oil in a heavy bottomed pan, when the oil is hot enough, add mustard seeds. When they splutter, add cumin seeds, crushed green chillies and curry leaves. Add soaked field beans and fry them for 2-3 minutes. Add turmeric powder, red chilli powder, garam masala powder, hing, coriander powder, goda masala and salt. Mix all the ingredients well. Add rice (just water nicely and water drained) and mix well. Add hot water, i.e. for 1 cup of rice add 2 cups of hot water and stir gently. Add a pinch of sugar. (Check the seasoning and adjust as per your taste). Bring it to a boil and then cover the pan with the lid. When most of the moisture is evaporated, then add 1 tsp of ghee and sprinkle some fresh grated coconut and chopped coriander leaves. Cover with lid and simmer for another 5 mins. The Dalimbi bhat is ready to be served.
