Peel and chop a ripe mango. Blend it in a blender until smooth. Strain the puree to remove any fibers and ensure a smooth cocktail.

In a shaker, combine the vodka, mango puree, fresh lemon juice, and simple syrup. Fill the shaker with ice, covering the liquid.

Secure the lid on the shaker and shake vigorously for about 15-20 seconds. The goal is to chill the mixture thoroughly and mix all the ingredients well.

Strain the cocktail into a chilled glass. You can use a rocks glass or a coupe, depending on your preference.

Garnish with a slice of mango on the rim of the glass or float it inside. Add a few mint leaves for a touch of color and freshness.

Serve immediately and enjoy the vibrant flavors of your Mango Vodka Sour.
