A hot drink made with rum, a sweetener such as sugar or honey and boiling water. Grog is served in a ceramic or glass mug and often garnished with a slice of lemon and a few whole cloves. It has long been considered a curative for colds but is generally consumed simply for its pleasure- and warmth-giving properties.
