My kids cook every Saturday to give Mum a day off. One cooks the main course and the other the dessert. It gets them into the kitchen and teaches them how to cook! And they love it. Check out the links for some excellent New Zealand food sites.
Fry the onions, leek, garlic, ginger and lamb until the lamb is brown Cut up and add the rest of the rest of the ingredients. Add some herbs and spices (garam marsala, cumin, cardamom, paprika. mustard seeds, lemon grass) Pressure cook for 1 1/2 hours.
