Measure out all ingredients and ensure you have ice cubes ready. Chill your serving glasses in the freezer for at least 10 minutes before preparation.

Add approximately 2 cups of ice cubes to the blender as your base layer. The amount of ice will determine the thickness of your final frozen dessert drink.

Pour in 4 ounces of piña colada mix over the ice cubes. This provides the creamy coconut-pineapple foundation of the drink.

Add 2 ounces of rum to the blender. Adjust the amount to taste preference or desired alcohol strength.

Pour in 1 ounce of sweet and sour mix to balance the sweetness of the piña colada mix with a citrusy tartness. Adjust the ratio to suit your preferred flavor balance.

Secure the blender lid tightly and blend on high speed until the mixture reaches a smooth, uniformly icy and creamy consistency with no large ice chunks remaining.

Taste the blended mixture and adjust ingredients as needed, adding more sweet and sour mix for tartness, piña colada mix for sweetness, or ice for a thicker texture. Blend again briefly if adjustments are made.

Pour the frozen mixture into the chilled serving glasses and serve immediately. Garnish optionally with a pineapple slice or cherry for presentation.
