Prep the glass: Rub a lime wedge around the rim of your highball glass, dip it in sugar if you’re feeling fancy, and fill it with ice.
Muddle the fruit: Drop 2-3 fresh cherries into a cocktail shaker and muddle gently to get those juices flowing.
Mix the base: Add vodka (if you’re using it), cherry syrup, and fresh lime juice to the shaker with the muddled cherries.
Shake it up: Toss in some ice, pop the lid on, and shake hard for about 15-20 seconds. You want it nice and cold.
Strain and top: Strain everything into your prepped glass. Top it off with club soda or lemon-lime soda—whatever you prefer.
Garnish and serve: Add a couple lime wheels and some fresh cherries. Give it a gentle stir with your bar spoon.
The finished drink should have a bright pink-red color and a lively fizz on top. Definitely serve it right away for the best bubbles.
