Use fresh pineapple and lime juice for best flavor. Full-fat coconut cream is key for creaminess. Adjust simple syrup to taste or omit for less sweetness. For a lighter version, substitute coconut milk but expect less creaminess. For a non-alcoholic version, replace rum and triple sec with pineapple soda and coconut extract. Chill glass before serving. Shake vigorously to emulsify ingredients. If too thick, add a splash of cold water or pineapple juice. Optional: add egg white for extra frothiness.
