I was given this curry recipe years ago by a local Indian family. It is so adaptable and so delicious that I make it all the time with whatever ingredients I have.
In the ingredients I have specified beef (due to the inflexibility of RecipeZaar!) but you can use beef, lamb or chicken, chickpeas or vegetables or any combination of these. Casserole beef cooks beautifully, it takes about an hour. Chicken with coconut cream is also lovely. Often we have it as a vegetarian/vegan curry with chickpeas and vegetables.
Serve with rice, yoghurt and naan bread if you like it!
