Place the drumstick pieces in a pan, add water (until it’s about 4 inches over the drumsticks)
Add ½ of the onions, chili, garlic, ginger, curry leaves, rampa leaves, cardamom, cinnamon coconut milk, all the mango and turmeric powder
Boil over a medium heat until the drumsticks are tender
Meanwhile, in another pot, cook the rest of the onions, chili, garlic, ginger, curry leaves, rampa leaves, cardamom, cinnamon and coconut milk until the onions are soft
Once the drumsticks are tender, transfer the ingredients from that pot into the second one
Simmer on low heat for about a minute, then take off the stove
Serve with roshi or rice
