Then continue to add the rum, the pineapple juice, and orange juice. Mix well with a bar spoon. Garnish with pineapple or orange slices.
Serve immediately.
Notes
For a special event, you can garnish with fresh flowers or mint. It looks very pretty.
If you would like to make a special presentation of this drink, stir it lightly, and let the person who drinks it stir it with a straw. That way they can see the gradient colors throughout the glass, beginning with the red.
