The biryani as it exists across the Indian subcontinent is not one preparation but a family of related preparations united by the layered rice-and-meat format and the dum (sealed steam) technique. Alford and Duguid document the key regional distinctions that differentiate these preparations: **Hyderabadi dum biryani:** - The meat is specifically raw when layered with the rice (kachchi biryani — "raw biryani") — both the meat and the rice complete their cooking simultaneously during the dum. The raw meat releases its juices during the dum, infusing the rice. This is the most technically demanding version — the timing must be exact for both components to finish simultaneously. **Lucknawi pukki biryani:** - The meat is fully cooked before layering — the dum serves only to combine the flavours and finish the rice. Less technical risk; the trade-off is slightly less flavour integration between the components. **Pakistani biryani:** - Less saffron, more whole spice. The yogurt in the meat base is a larger proportion, producing a thicker, more acidic base. The fried onion (birista) is applied more generously. **Sri Lankan biryani (buriyani):** - Uses pandan leaf and the Sri Lankan spice vocabulary rather than the North Indian set. The rice is sometimes slightly shorter-grain than basmati.

Goan cooking's relationship with vinegar — brought by the Portuguese in the 15th century and integrated into Goan culinary DNA — produces a family of preparations that are unique in Indian cooking. Not just vindaloo but the full range of Goan rice vinegar and coconut vinegar preparations that use acid as a primary flavour rather than merely as a technical agent.

Kerala's coastal cooking — based on the most abundant coastline in India, with the highest per-capita fish consumption of any Indian state — has developed a preparation system that treats different fish varieties with fundamentally different techniques: oily fish (sardines, mackerel) are dry-fried or pickled; firm-fleshed fish (kingfish, snapper) are poached in thin coconut milk curries; delicate fish (pearl spot, karimeen) are smeared in paste and pan-fried.
