This lamb dish combines two types of spiced lamb and is served with cumin potato cakes, aubergine and mint chutney.
Equipment and preparation: you will need a tandoor oven.
For the lamb shoulder, heat half of the oil in a large pan and brown the lamb shoulder with the cumin seeds until nicely coloured. Set aside in a large bowl.
Heat two tablespoons of oil in a large pan and fry the sliced onion with the ginger, garlic, chilli, and all the spices.
Add the lamb to the pan and enough stock to just cover the meat. Put a lid on the pan and cook for 2-2½ hours, or until tender.
For the barbecue rack of lamb, make a paste by blending the ginger and garlic in a food processor. Transfer to a bowl and stir in the oil, yoghurt, lime zest and lime juice. Season to taste with salt and freshly ground black pepper.
Cover the lamb racks with the paste and leave to marinate for an hour, or longer if time allows. Heat a tandoor oven.
Thread the lamb racks onto skewers and roast in the tandoor oven for 12-15 minutes. Carefully remove the meat from the oven and allow to rest before carving. Carve in half to serve.
For the cumin potato cakes, steam the potatoes for 25 minutes, or until softened. Once cool, grate half of the potatoes into a bowl and roughly crush the remaining half in a separate bowl. Combine both textures of potatoes.
Stir in the ground cumin powder, chilli, garlic and coriander. Season to taste with salt and freshly ground black pepper. Shape into four patties or cakes using your hands.
Heat the butter and oil in a pan and fry the cumin potato cakes until lightly browned.
For the aubergine, heat the oil in a large pan and roast the cumin seeds with the garlic, ginger, chilli and onion for a few minutes until softened.
Add the turmeric, salt to taste and stir in the aubergine and a squeeze of lemon juice. Heat for 2-3 minutes, reduce the heat and cook slowly for 15-20 minutes. Stir in chopped coriander when ready to serve.
For the lamb shoulder, remove the lamb from the pan and blend the sauce until smooth. Strain the sauce, re-heat and season to taste with salt and pepper. Put the lamb back into the sauce to warm through before serving.
For the mint chutney, blend the mint, coriander, chilli, garlic, lime zest and juice in a food processor until smooth. Add caster sugar to taste and a little oil, pulse again to combine. Season to taste with salt and freshly ground black pepper.
To serve, serve the aubergine, potato cakes, mint chutney, two bones from the rack and a piece of shoulder and some sauce on each plate.
