*The vegetables generally put in avial are, Yam, Snake-gourd, Raw Banana, Drumsticks, Pumpkin, Melon, Carrot and Raw mango. If u don’t get some vegetables, substitute with whatever u get.... use Chinese okra (beerakai), cucumber (peeled), Zuchini, Frozen drumsticks, French beans etc. ** If u r using raw mango, u can reduce the amount of yogurt accordingly. Cut all the vegetables into 2-inch long pieces. Start cooking with whichever takes more time to cook (yam, raw banana etc.) adding just enough water to cook and turmeric. Then add all other vegetables one by one. Meanwhile grind coconut, cumin seeds and green chilly to get a coarse paste. When vegetables are about ¾ th done, add coconut paste, yogurt and salt and cook on low flame till all the water is absorbed. Pour coconut oil on top and garnish with curry leave. Serve hot with rice.
