Hi Becky I use beef because I can't get hold of lean lamb mince in any supermarkets in Cornwall. My husband has made it with normal lamb and it is lovely but obviously I can't have it due to the fat!! But the beef is still nice. I find that the meat can go a bit dry and I only ever think it needs 45 mins in the oven rather than 1 hr 20 like the recipe says. But I make a garlic sauce with blf mayo, fat free natural yoghurt, lemon juice and crushed garlic, without a sauce it would be dry. But I have it loads and love it.
