Beef Bhuna

Heat mustard oil in a heavy pot until smoking, then let it cool slightly. Add whole spices (cardamom, cinnamon, cloves, dried chilies) and fry for 30 seconds until fragrant.

Add sliced onions and cook on medium-high heat for 15-18 minutes, stirring frequently, until they turn a deep, dark golden brown. This caramelization is the foundation of all flavor in a bhuna.

Add ginger-garlic paste and cook for 2 minutes until raw smell disappears. Add all ground spices (cumin, coriander, chili, turmeric) with a splash of water and cook the masala for 5 minutes until oil separates.

Add the beef cubes and sear on high heat for 5 minutes, stirring to coat every piece with the spice paste. The 'bhuna' technique means frying the meat in the dry spice paste until it catches and caramelizes.

Add pureed tomatoes and salt. Continue cooking on medium heat, stirring frequently and adding small splashes of water as needed to prevent sticking. The key is to let the sauce reduce and concentrate repeatedly.

Reduce heat to low, cover, and cook for 1-1.5 hours until the beef is fork-tender. Every 20 minutes, uncover and bhuna (stir-fry) the meat again, scraping up the fond, until the gravy becomes thick, dark, and clings to the meat.

Finish with garam masala, garnish with fresh cilantro and sliced green chilies. The final bhuna should have almost no liquid sauce, just a thick, dark spice coating on each piece of tender beef. Serve with paratha or steamed rice.
