Chill your glasses. Pop hurricane or highball glasses in the freezer for 10 minutes.
Cold glasses help the drink stay thick and frosty.
Measure your base. Add 2 ounces light rum and 1 ounce dark rum to a blender. If you prefer a lighter drink, stick with just 2 ounces light rum.
Add fruit and cream. Add 2 cups frozen pineapple, 1/2 cup coconut cream (or 3–4 tablespoons cream of coconut if you want it sweeter), and 1/2 cup pineapple juice.
Brighten and balance. Squeeze in 1/2 ounce fresh lime juice and add a small pinch of salt. This keeps the drink lively, not heavy.
Adjust thickness. If your pineapple isn’t fully frozen or you like a thicker texture, add 1/2 to 1 cup of ice.
Blend until smooth. Start on low to break down the pineapple, then blend on high for 20–30 seconds.
You want a creamy, soft-serve consistency with no fruit chunks.
Taste and tweak. If it’s too tart, add a teaspoon of simple syrup or cream of coconut. If it’s too thick, splash in more pineapple juice. If it’s too strong, blend in more frozen pineapple.
Serve and garnish. Pour into chilled glasses.
Garnish with a pineapple wedge and a cherry, or sprinkle a little toasted coconut on top for extra aroma.
Make it a mocktail. Skip the rum and add 1–2 ounces extra pineapple juice plus a dash of coconut water. Keep everything else the same.
