Start the Base: Heat oil in a kadai (wok) on medium heat. Once hot, add the cumin seeds and let them sizzle.
Sauté Onions: Add the 3 finely chopped onions and sauté them well until they turn soft and light brown.
Add Aromatics: Add the crushed ginger-garlic-green chilli paste. Sauté for another 2-3 minutes until the raw smell is gone.
Cook Tomatoes: Add the finely chopped tomato and cook for about a minute until it becomes soft.
Add Dry Spices: Turn the heat to low. Add the Agri masala, cumin-coriander powder, garam masala, turmeric powder, and salt.
Cook the Masala: Sauté the spices on low heat for 3-4 minutes until the oil starts to separate from the masala. This step is key to a flavorful curry.
Add Flavour: Add half of the chopped coriander and the 3 pieces of kokum. Give it a good mix.
Simmer the Gravy: Add 1/2 cup of warm water to the pan. This helps cook the masalas properly. Cover the kadai and let the gravy simmer on low heat for 5-7 minutes.
Add the Prawns: Uncover the pan. You will see a nice, thick masala base. Now, add the cleaned prawns (Kolambi).
Mix and Cook: Mix everything well, ensuring the prawns are coated in the masala. Keep the heat on low.
Final Cook: Add the remaining chopped coriander leaves and mix again. Cover the pan and let the prawns cook on low heat for 10 minutes. Do not overcook them.
Serve: After 10 minutes, turn off the heat. Your Masaledar Kolambi is ready! The curry will thicken slightly as it cools.
