In a high-speed blender, combine pumpkin puree, apple juice, and pineapple juice. Add cinnamon, nutmeg, and ginger. Blend on high for 30-60 seconds until smooth.

Taste the juice and adjust sweetness with sugar as needed. Blend again until fully mixed.

For a slushy drink, add ice and pulse until frothy. For warm juice, heat in a saucepan over low heat for 5-7 minutes, stirring occasionally.

Pour the juice into glasses and garnish with a cinnamon stick or fresh apple slice.

Allow any leftovers to cool before transferring to an airtight container for storage.
