Fragrant aged basmati rice layered with spiced meat, saffron-infused milk, and sweet caramelised onions, sealed and slow-cooked in dum style.
Mix the mutton with the yogurt, ginger-garlic paste, chili powder, and salt; rest for 1 hour.
Heat the mustard oil until smoking, cool slightly, and fry the onions with the bay leaves until deep brown.
Add the marinated mutton and bhuna on medium-high heat for 10 minutes until the masala clings and the oil separates.
Add 1 cup hot water, cover tightly, and cook for 45 minutes until the mutton is tender and the gravy is thick.
Sprinkle the garam masala and serve with luchi or steamed rice.
