Prepare the Fruit Juice:

Squeeze fresh juice from a grapefruit until you have about 1/2 cup.

Muddle the Strawberries:

In a cocktail shaker, muddle the strawberries with the simple syrup to release their juice and flavor.

Mix the Cocktail:

Add the freshly squeezed grapefruit juice, vodka, and a handful of ice cubes to the shaker.

Shake vigorously for about 15 seconds to combine all the flavors.

Strain and Serve:

Strain the mixture into a chilled glass filled with ice. This helps remove the strawberry pulp and seeds, leaving a smooth drink.

Garnish and Enjoy:

Garnish with a slice of grapefruit, a strawberry, and a sprig of mint if you like.

Serve immediately and enjoy your fresh, vibrant cocktail.
