Lamb biryani

Preheat the oven to 180oC, gas mark 4. Heat 1 tbsp oil in a large frying pan over a medium-high heat. Fry the onion with a pinch of salt, stirring regularly, for about 15 minutes, until crisp and golden.

Meanwhile, in a small, lidded casserole dish or saucepan, heat 1⁄2 tbsp oil over a medium-high heat. Fry the spices from the biryani kit for 20 seconds, add the lamb and fry for 1-2 minutes to seal, ensuring all the cut surfaces of the meat are well browned. Add the sauce from the kit and 3 tbsp water. Stir and simmer gently over a medium heat for about 10 minutes, until the meat is coated in a creamy sauce.

Massage the rice packet from the kit to break up any clumps, then layer the rice evenly over the lamb. Sprinkle over the crispy onions and chopped butter, then cover the pan with a lid and transfer to the oven for 20 minutes.
