Rub roast all over with sliced garlic and salt and pepper; discard garlic pieces and place pork roast on rack in a baking or roasting pan. Roast at 325° for 2 1/2 to 3 hours or until an inserted meat thermometer
registers 175°. Meanwhile, combine all remaining ingredients
in a stainless steel saucepan; bring to a boil. Remove from heat.
Halfway through the roasting, begin basting the roast every 15 minutes
with cranberry sauce mixture. Serve pork thinly sliced with the remaining sauce. Serves 6.
