Mix garlic, pepper and vinegar; rub roast. Pierce meat all over with fork. Place in roasting pan and arrange bacon slices across the meat. Bake, uncovered, at 350F for 1/2 hour. Add water as needed. At the end of cooking time, place vegetables around roast, add currant sauce and bake 1 to 1 1/2 hours (depending on how you like your meat).
