Grand Marnier is a delicious orange-flavored liqueur and is absolutely divine in hot cocktails, especially a hot toddy. Simply make a hot toddy as you normally would: a mug full of hot water, a squeeze of lemon, a spoonful of honey, and an ounce of bourbon, then add a splash of grand Marnier for a delicious citrusy cold-weather beverage that'll warm you up in an instant. If you'd like, substitute the lemon for an orange for an extra-sweet orange taste. Also add a dash of cinnamon, or a bit of ginger, for aroma and their extra health-boosting qualities.
