This recipe is from Brigitte Hafner. When I made it I found I had to add quite a bit of water in the last 15 minutes to stop it getting too dry, just keep an eye on it and stir frequently. I used rump steak as that was all I had, but I marinaded it for 24 hours in a tenderising marinade and it was absolutely amazing. I made this in a nonstick wok so you may like to use more oil if you don't have one of these. Also, I used pre-cooked potatoes to make it a little faster and just reheated them in the curry (but they would taste nicer cooked in).
