Peel, halve and core pears. Place in a large round baking dish or pie plate, with stem-ends toward the center. Pour orange juice over pears. Cover with foil and bake for 30 minutes. Uncover and sprinkle with remaining 1 tablespoon sugar. Bake until pears are tender and the juice is reduced to a glaze, basting from time to time with juice, 20 to 30 minutes more. Set aside.
