Preheat oven to 375 degree F. With a mortar and pestle, slightly crush caraway seed and whole black pepper. Or, in a blender container combine caraway seed with whole black pepper; cover and blend on high for 30 seconds. Stir in lemon peel and salt. Skewer neck skin to back; tie legs to tail. Twist wings under back. Rub caraway mixture over entire bird and under skin of breast.

Roast, uncovered, 1-1/4 to 1-3/4 hours or until drumsticks move easily and meat is no longer pink or thermometer registers 180 degrees. Remove chicken from oven. Cover and let stand 10 minutes. Carefully drizzle lemon juice over chicken before carving. Serve with lemon slices, if desired.
