I found some unspecified "stewing lamb" on special offer in Waitrose, looked like sliced shoulder to me, and it was english, so I thought it would be a good candidate for this nice rich, stew. I think it cost just over £2 and was ample for two of us. I'm not sure how authentically Italian it is, but I've always known it as such, probably from the days when anything with tomatoes in it was "Italian". Anyway it's certainly tasty and easy to do, especially if you have a supply of home made tomato sauce in the freezer as I recommended back in September.
1 lb/500g stewing lamb
2 garlic cloves chopped
sprig of thyme
half pint/250g tomato sauce from your stash in the freezer, otherwise use passata
1 tin of butter beans
Brown the lamb in some olive oil, add the roughly chopped onions, garlic and carrots, and continue to fry for a few minutes. Pour over the tomato sauce, add the thyme, season well and put in medium oven until the lamb is tender and falling away from the bone.Add a spot of water if it gets a bit dry. Timing will depend on the cut, but allow about an hour for shoulder. Add the drained butter beans and return to the oven to heat through. Check seasoning and sprinkle generously with parsley before serving with a green veg, kale or brocolli perhaps. Once prepared it will sit happily in a low oven until you're ready to serve.
