Begin by preparing your citrus. Juice one fresh orange to get approximately 2 ounces of pulp-free juice. This fresh juice is key to the vibrant flavor of your Orange Crush.
In a cocktail shaker, combine the vodka, orange liqueur, and freshly squeezed orange juice. Add a handful of ice to the shaker.
Secure the lid on the cocktail shaker and shake vigorously for about 15-20 seconds until the outside of the shaker feels well-chilled. This ensures your drink is perfectly cold and well-mixed.
Fill a tall glass (like a Collins or highball glass) with fresh ice. Strain the mixture from the shaker into the prepared glass.
Top off the drink with the club soda or seltzer water. This adds the signature 'crush' effervescence and lightness to the cocktail.
Gently stir the drink once to combine the club soda with the rest of the ingredients. Be careful not to stir too vigorously, as you want to preserve the bubbles.
Garnish your Orange Crush with a fresh orange slice perched on the rim of the glass. Add a maraschino cherry for an extra pop of color and sweetness, if desired.
Serve immediately and enjoy the refreshing burst of citrus!
