Cut orange slices in half. Using a wooden toothpick, poke holes in the peel of each orange slice at 1/2-in. intervals. Insert a clove into each hole; set aside.
In a large saucepan, bring apple juice and cinnamon stick to a boil. Reduce heat; cover and simmer for 5 minutes. Stir in the pineapple juice, honey, lemon juice, zest and nutmeg; return to a boil. Reduce heat; cover and simmer for 5 minute.
Discard cinnamon stick. Garnish with orange slices. Serve warm with additional cinnamon sticks for stirrers if desired.
