Combine all ingredients in a shaker and fill it with ice.

Shake it for 20-30 seconds and then strain to avoid getting ice cubes in the drink.

First strain it through a regular bar strainer and then a fine strainer (this is called double straining).

Next, pour it into a coupe glass that comes straight from the freezer, so it is ice cold.

Garnish optionally with a pineapple leaf.
