4ounceslemon-lime soda (such as Sprite–and I've used Fresca)
1ouncegrenadine (I use Rose's; usually located near the soda water and other mixers in the grocery store)
1lime wedge, squeezed
1maraschino cherry (still worth making if you don't have cherries!)
Instructions
Fill a double old-fashioned or highball glass halfway with ice cubes. Pour in the vodka, lemon-lime soda, and grenadine. Give the lime wedge a good squeeze and stir. Top with a cherry and enjoy!
