Cook's Notes
Use fresh, high-quality spices for best results. The two spice mixes serve different purposes—one for marinating and cooking the meat, the other for infusing the milk. Proper sealing of the pot and the two-stage dum cooking are crucial for achieving authentic results. Rice doneness is key; it should be partially cooked before layering.
