Not yet eaten the lamb, CC, other than to test it for softness. I cooked it in a large round cast-iron casserole (Le Creuset or similar), starting by softening the onions until they were transparent, then adding the masala, stirring, mixing and cooking that with the onions until I judged that it was ready, then added the lamb and stirred and lifted it until all was evenly coated. I then cooked it on a low heat with the lid on, stirring occasionally (after removing the lid !) and finally turned it off while I went off to the hotel. When I got home circa 23:00 I checked that it was done (by eating one piece). I noticed that the initial strongly-spiced and "edgy" flavour has now gone and I am left with a much milder spicing, so I will probably use it to make a more conventional curry (with g/g paste, fresh spices and base) when I am ready to eat it. Not yet ready to try it today
