Let's show you how easy it is to make this drink. In a tall highball glass, add a handful of ice and pour in the vodka and grenadine.
Top with chilled lemon-lime soda, such as Sprite or 7UP. To combine all the ingredients, gently stir with a bar spoon.
Garnish with a maraschino cherry and a lime wedge or lime wheel. Don't be shy with the cherries here. You can't have enough extra cherries.
