Sabzi means greens, and in this qorma the greens are the sauce. The spinach is chopped fine and cooked down slowly under a lid until it has collapsed into something dark and dense. The lamb is cooked separately with onion, garlic and a long red chilli until tender, then folded into the spinach with a cup of its broth and a handful of coriander and garlic chives fried in oil, and the two simmer together for a final quarter of an hour. It is eaten with plain white rice and a spoonful of yoghurt, and it is the dish Afghan families serve at Nowruz, the spring new year. This version cooks the lamb in a pressure cooker; a heavy pot and an hour on the hob do the same job.

INGREDIENTS
- 250 ml sunflower oil (divided)
- 1 large onion (finely diced)
- 2 garlic cloves (finely chopped)
- 1 long red chilli (thinly sliced)
- 1 kg boneless lamb leg (in chunks)
- 750 ml water (for the lamb)
- 2 tbsp salt (for the lamb)
- 1 kg bunched spinach (roots and stalks removed)
- 125 ml boiling water (for the spinach)
- 80 g fresh coriander (finely chopped)
- 60 g garlic chives (finely chopped)
- salt (to taste)
- plain white rice (to serve)
- plain yoghurt (to serve)
METHOD
- Heat half the oil in a pressure cooker over a high heat and fry the onion, garlic and chilli for about 5 minutes, until golden.
- Add the lamb and sear until browned. Add the 750ml water and 2 tbsp salt, close the lid and bring up to high pressure.
- Turn the heat to low and cook for 20 minutes, then take off the heat and let the pressure drop naturally.
- Meanwhile, chop the spinach finely and put it in a large pan with the boiling water. Cover and cook over a medium-high heat for about 20 minutes, stirring now and then, until all the liquid has gone.
- Heat the remaining oil in a frying pan over a medium heat and fry the coriander and garlic chives for about 5 minutes.
- Add the lamb, 250ml of its cooking liquid and the fried herbs to the spinach. Stir, and simmer on a low heat for 15 minutes. Season with salt.
- Serve with plain rice and a spoonful of yoghurt.
