Place the cinnamon sticks, ground cloves, allspice berries, orange peel and lemon peel in a medium saucepan. Pour in the maple syrup and apple juice, then bring to almost a boil. Reduce the heat to low and simmer for 30 minutes. Remove from the heat and serve in mugs with apple slices and orange twists for garnish. Add a splash of rum for an adults-only version! Yum, yum, yum. (Adapted from AllRecipes.com.)
