• Quick one-pot: Skip the layering and cook it all in one pot.

Tips

• "A yoghurt marinade tenderises the meat" is half right, and kebab already says so about the same claim. What marinades do carries a section headed "Acid does not tenderise." Kebab states the same correction in its own words, against the same claim. What gets inside meat is salt; acid stops one to three millimetres in. So the tenderness the line below credits to the yoghurt is really the work of the salt in the marinade and of the dum that follows.
• There is still a reason it has to be yoghurt, and it suits this dish better than the false one. The same guide treats yoghurt separately: mild acid, calcium and milk protein together act far more gently than vinegar, and its thickness keeps it clinging to the surface. More to the point here, its lactose and protein feed the Maillard reaction, so it colours well (browning) — and in a biryani the meat takes its colour before the dum, with that colour carrying much of the aroma. A yoghurt marinade can also sit overnight without wrecking the surface, which a vinegar one cannot; the guide's instruction is not to put the two on the same timetable.
• The 70% means there is steam left to finish it. What cooks the rice inside a sealed pot is not water but trapped steam, and steaming gives the force behind it: the latent heat one gram of steam releases as it condenses is more than five times what a gram of water gives off cooling from 100°C to 60°C. That is why a little liquid in the base can finish rice at the top. Note also that "parboiled rice" is not rice cooked this way — jollof rice draws the distinction: that is a grain steamed in its husk and dried before milling, a finished product, where this is simply the verb.
• The sealed lid deliberately inverts that guide's commonest failure. Steaming says the drip off the lid is the commonest failure — dumplings burst where it lands, steamed buns come out blotched — and prescribes a cloth under the lid or setting it slightly ajar. In a dum, that drip is the whole of the water the rice has left to finish on. There is no other liquid in the pot, so following the prescription would stop the dish working.
• Folding gently comes out of the same guide. Steam applies no mechanical force. Unlike hot water it does not push its way in; it flows along whatever gaps exist and condenses on the surfaces it reaches, so density decides the cooking time. Layering loosely is therefore a cooking condition, not presentation, and a packed pot cooks unevenly. Maqluba is the opposite case — it packs the pot on purpose to build a dome, and uses this dish as its control: "Kabsa and biryani are both served out of the pot the way they went into it."
• Basmati is the rice — long and non-sticky. Parboil to 70% and let the dum finish it.
• Fried onions (birista) are key to the sweetness and aroma — be generous.
• Saffron milk for color and scent; a yogurt marinade tenderizes the meat.
• Low heat + a sealed lid (dum) is the secret — it steams and traps the aroma. Never high heat.
• Rest 10 minutes, then fold gently so the grains stay intact.
