Lamb dopiaza means lamb with double onion. It is like a korma, with the meat braised in yoghurt, but has a very different flavour and texture because of the onions. It is also very easy to prepare, partly because it is a one-pot dish.
Toast the coriander seeds, cumin seeds, cloves, cinnamon, black peppercorns and cardamom pods in a small pan on medium heat. When aromatic, remove from heat, allow to cool, then grind to a coarse powder.
for the gravy
Heat the ghee in a deep, heavy-bottomed pot on medium heat.
Place the chopped onions, garlic, ginger, the ground spices, turmeric, Kashmiri chillies and salt into the pot and mix well. Add the lamb, then add the yoghurt one spoon at a time whilst gently mixing. Add the water and reserved lamb bones and gently bring the pot to boil, stirring continuously.
Cover the pot, reduce the heat to very low and simmer for one and a half hours, stirring occasionally.
to finish
Uncover the pan and remove the lamb bones then add the sliced onion. Mix well and raise the heat to medium. Cook for another 30 minutes, stirring frequently. The gravy should reduce and the onions and the lamb should soften.
The curry is cooked when you have a thick rich creamy sauce, with the lamb soft enough to cut with a fork.
to serve
Turn into a serving bowl and dress with the coriander leaves. Serve.
notes
Ask your butcher to bone the shoulder and cut the meat into 5cm chunks. Retain the bones as you will cook with them.
The time taken to reduce the sauce will depend on the moisture content of the meat, and how hot you keep the pot. Too high a heat and you will risk burning the dish. Too low, and it will take too long to reduce. If you don’t have to keep stirring every few minutes it is probably too low.
