Sear veal in bacon dripping until all sides are nicely browned.
Place in a roast pan.
Mix the mustard, sage, sugar, salt, pepper, water and vinegar together, and pour this over the meat.
Arrange the slices of bacon over the top and sides securing them with toothpicks where necessary.
Roast in a 350F oven, basting occasionally until veal is well cooked.
Allow about 35 to 40 minutes per pound or until a meat thermometer registers 170F
