Mix the flour, mace and seasoning together.Toss the diced meat in the seasoned flour.
Heat the oil in a large pan and brown the meat in batches. Then transfer to a large flameproof casserole dish. Add the onions, garlic and celery to the pan and saute for 3-4 minutes, then add mustard and wine. Bring to the boil and reduce for a few minutes.
Pour the lot over the meat in the casserole. Add the port, stock, herbs and half the cranberries.
Cover and cook gently for approx. 2 hours until the meat is tender, or cook in the oven Gas Mark 4, 180C, 375F for about the same time.
15 minutes before the end of cooking time add in the remaining cranberries. Check the seasoning before serving and garnish with sprigs of watercress and orange.
Lovely with creamy mashed potatoes and crusty bread toasted and drizzled with olive oil and chopped herbs.
