Simple lamb rogan josh

Ingredients

6 garlic cloves, roughly chopped
1 large onion, roughly chopped
thumb-size piece fresh ginger, peeled and roughly chopped
1 tsp ground cinnamon
2 tsp ground cumin
2 tsp ground coriander
1 tbsp paprika
1 tsp chilli powder
1 tsp salt
1 tbsp tomato purée
4 tbsp vegetable oil or ghee (clarified butter)
1kg/2¼lb casserole lamb, cut into bite-size cubes
8-10 cardamom pods, lightly crushed with the back of a spoon
300ml/10fl oz lager

Method

1. In a food processor, blend together the garlic, onion, ginger, all of the ground spices, salt and tomato purée.
2. Heat the oil or ghee in a large saucepan or flameproof casserole and add the lamb pieces and cardamom pods. Quickly fry until the lamb is browned all over. This may need to be done in 2 batches, depending on the size of your pan. Stir in the spicy paste and cook for about 5 minutes, stirring frequently. Pour in the lager and bring to a simmer. Cover with a lid and cook for about 1-1¼ hours, stirring occasionally, until the sauce has thickened and the lamb is lovely and tender. Leave the dish to relax for 5 minutes before serving.
