Start by preparing your kofta balls. In a large mixing bowl, combine the beef, 1 diced onion, breadcrumbs, cilantro, garlic, beaten egg, ginger, 2 teaspoons ground coriander, 1 ½ teaspoons cumin, 1 ½ teaspoons salt, and 1 teaspoon turmeric. Using your hands, mix all the ingredients until well combined. Shape them into 40 meatballs, about 1 heaping tablespoon each, and place them on a parchment-lined baking sheet.

In a large pot, heat 2 tablespoons of oil over medium-high heat. Working in batches, sear the meatballs for 5-6 minutes until they are browned on all sides. Once done, transfer them to a plate with a slotted spoon, and repeat with the remaining meatballs.

Make the curry. Saute the two remaining diced onions in the same pot over medium heat for 12 minutes. Then add the remaining 1 ½ teaspoons salt, 1 teaspoon turmeric, 2 ½ teaspoons of ground coriander, 1 ½ teaspoons of cumin as well as the garam masala and curry powder. Add 2 tablespoons of water, give everything a good stir, and fry for 2-3 minutes, ensuring the spices do not burn. Then add in the tomato puree, tomato paste, and 2 ⅓ cups water. Mix well.

Gently add in your kofta balls, increase the heat and bring the curry to the boil. Lower to a simmer, and cook for 45-55 minutes, stirring intermittently until the cooking liquid has reduced into a thick sauce. Serve warm with rice.
