Cook cinnamon stick, cloves, and ginger in a Dutch oven over medium heat, stirring constantly, 2 to 3 minutes or until cinnamon is fragrant.
Gradually stir in juices. Bring to a boil over medium-high heat; reduce heat to medium-low, and simmer 15 minutes. Pour mixture through a wire-mesh strainer into a heat-proof pitcher; discard solids. Stir in almond liqueur; serve warm. Garnish, if desired.
