Prepare the Drumsticks: First, wash the drumsticks. Cut them into 2-3 inch pieces and peel off the tough outer skin or "strings".
Pre-cook the Drumsticks: Add the drumstick pieces to a pot with about half a glass of water. Cover and boil for 10-12 minutes. Don't cook them until they are completely mushy; they should be just tender. Keep the drumsticks and the leftover water aside.
Start the Tadka: Heat oil in a kadai (pan). Once hot, add mustard seeds. When they pop, add cumin seeds, asafoetida, and curry leaves.
Sauté Onions: Add the chopped onions and fry them well until they become soft and light brown.
Add Ginger-Garlic-Chilli: Add the crushed paste of ginger, garlic, and green chilli. Sauté for a minute until the raw smell is gone.
Cook Tomatoes: Add the chopped tomatoes and salt. The salt helps the tomatoes cook down faster. Sauté until they are soft.
Add Dry Spices: Lower the heat. Add the turmeric powder, garam masala, cumin-coriander powder, and Kanda Lasun Masala. Stir and cook the spices for about 30 seconds.
Add Peanut Powder: Add the roasted peanut powder and some fresh coriander to the masala. Mix everything well.
Combine: Now, add the pre-boiled drumsticks along with the water they were cooked in. Gently stir to coat the drumsticks with the masala.
Simmer (The Final Step): Cover the pan and let this Shevgyachya Shengachi Sukki Bhaaji simmer on low heat for 10 minutes. This helps the drumsticks absorb all the wonderful flavours.
Serve: Open the lid, give it one final mix, and your delicious drumstick stir-fry is ready to serve hot!
