Shake and Chill: Add vodka, grenadine, orange juice, and cherry juice to a cocktail shaker filled with ice. Shake vigorously for about 15 seconds until well chilled.
Pour and Serve: Fill two lowball glasses with crushed ice. Strain the chilled mixture evenly into each glass, filling about ¾ full.
Add Soda: Top each glass with cherry-flavored lemon-lime soda to bring the perfect bubbly finish.
Garnish and Enjoy: Drop in maraschino cherries or rim glasses with red sugar for extra holiday flair.
