Prepare your glass: Grab a tall glass, like a highball or a Collins glass, and fill it about three-quarters of the way with ice cubes. The ice helps create those distinct layers of color.

Add the grenadine: Pour the grenadine into the glass first. It’s the heaviest ingredient, so it will naturally sink to the bottom.

Mix lemon vodka and soda: In a separate cup, mix your lemon vodka with a splash of lemon-lime soda. Slowly pour this over the back of a spoon into the glass. This will help create the middle layer.

Add the Blue Curaçao: Now, take your Blue Curaçao and again, slowly pour it over the back of a spoon to make the top layer of the drink. This will float on top, giving your cocktail that signature red, white, and blue look.

Garnish and serve: If you want to add a little flair, pop a maraschino cherry on top or on the rim of the glass. And voila—you’re done! Sip slowly and enjoy the nostalgia in every layer.
