Fragrant layered lamb and saffron rice

Biryani is one of those dishes that carries a long story in every mouthful. The name comes from a Persian word for fried or roasted, and over the centuries it travelled through Mughal kitchens, then into homes across South Asia and beyond. Every family has its own version, and this one is a sensible, British-kitchen take: lamb cooked slowly with whole spices, then layered with rice and baked until everything settles into itself.

The part I love most is the onions. You fry the sliced onions until they are a light gold, then set a quarter of them aside to go deep brown in a separate pan. Those dark, sweet onions scattered over the top are what make the finished dish look and taste like a proper celebration. Don't rush them. Pale onions won't give you the same depth, and it's worth the few minutes at the stove.

A word on the lamb. Boneless leg is lean and cubes neatly, and it needs that long, gentle simmer with the lid on to turn tender. If you lift the lid too often, the steam escapes and the meat takes longer. Stir the yogurt in once the lamb is soft, so it doesn't split in the heat. Lamb is a good source of protein and iron, and a dish like this, built around a generous amount of meat with plenty of spice, feels filling without needing much else on the side.

For the saffron, soak the threads in boiling water while you cook, and drizzle that liquid over each rice layer. It gives the rice a gentle golden colour and a floral note that is hard to replace. Cooked basmati should be fluffy and separate, so rinse it well before you start and cook it only until just tender.

Leftovers keep well. Cool the biryani within an hour or two, then store it in the fridge for up to two days. Reheat it with a splash of water, covered, until steaming all the way through. A spoonful of cold yogurt, a few chopped coriander leaves and a squeeze of lime make it feel fresh again.

For a simple accompaniment, a bowl of cucumber and mint raita or a quick tomato and onion salad goes well. If you want something lighter to start, a bowl of Chickpea and Lentil Soup with Sourdough makes a warming first course, and for dessert a light Creamy cardamom vermicelli pudding with pistachios echoes the spices in the rice.
