Step 1

Chill your cocktail glass in the freezer to keep your drink cool.

Step 2

In a blender, combine the frozen mango chunks and a little bit of water to help blend it smoothly. Blend until the mango is pureed.

Step 3

In a cocktail shaker, combine the white rum, lime juice, simple syrup, and about 2 tablespoons of the mango puree. Add a handful of ice cubes to the shaker.

Step 4

Secure the lid on the shaker and shake vigorously for about 15 seconds. Shaking not only mixes the ingredients but also chills and dilutes the drink slightly for a smoother taste.

Step 5

Strain the mixture into the chilled cocktail glass. You can choose to strain it finely to remove all ice shards or leave some if you prefer a bit of texture.

Step 6

Garnish with a slice of lime or a small wedge of mango on the rim of the glass for an extra touch of tropical flair.
