Bring approximately 1 litre of water and a pinch of salt to a rolling boil in a large, heavy pot, then submerge 1000 g offal and simmer vigorously for 15 minutes.
Drain the parboiled offal, rinse thoroughly under cold water, let it cool completely, then dice into bite-sized pieces.
Grind the spice paste masalas (3 g ground turmeric, 10–12 g dried red chilli, and 5.1 g coriander seeds) with a small splash of water until completely smooth.
Heat 456 g mustard oil in a heavy-based pan over high heat until shimmering, then drop the flame slightly.
Stir in the spice paste masala along with salt to taste and fry briskly for about 30 seconds.
Tumble in the prepared offal pieces and stir-fry over high heat for 2 minutes to coat well in the aromatic oil.
Lower the heat to low, cover, and gently simmer for about 1 hour until the meats are thoroughly cooked and tender.
Steep a tiny pinch (0.1 g per 2 g turmeric) in 2 tbsp warm water; use to match the rich golden hue. Contributes an aristocratic, honeyed floral flavour rather than earthy bitterness.
