Coat the meat in the flour and shake off any excess.
Heat the oil/butter in a heavy-based dish, then brown the meat. Add the celery, onion and bay leaf – season with salt& pepper, then pour in the water and wine. Bring to the boil, put a lid on, and gently simmer at the lowest setting for 2 hours.
Meanwhile, slice the mushrooms and dice the potatoes & carrots. Add these to the stew for the last 25-30 minutes of the cooking time.
When the vegetables are cooked through and the sauce is thick, the stew is ready to serve.
Serve with crusty bread and a green salad.
