Fragrant aged basmati rice layered with spiced meat, saffron-infused milk, and sweet caramelised onions, sealed and slow-cooked in dum style.
Fry the onion slices in the ghee until crisp and golden and reserve half for garnish.
Mix the mutton with the yogurt, ginger-garlic paste, and salt and rest for 1 hour.
In the same ghee, add the green cardamoms, then the marinated mutton, and brown well.
Add the cashew paste, cover, and cook on low heat until the mutton is tender, adding water as needed.
Stir in the garam masala and crushed birista and serve with roomali roti.
