Start by placing your fresh blueberries, mint leaves, granulated sugar, and lime wedges into a sturdy highball glass. Now, it's time to muddle. The key is to be gentle. You want to press down and twist just enough to release the juice from the blueberries and the fragrant oils from the mint. You'll know you're done when the berries have popped and the air is filled with a fresh, minty aroma.
Next, fill the glass to the top with ice cubes. Don't be shy with the ice; it keeps the drink perfectly chilled and ensures it dilutes at just the right pace. Pour your two ounces of white rum directly over the ice. Watch as it cascades through the muddled fruit and mint, beginning the beautiful fusion of flavors.
Finally, top your drink with chilled club soda, pouring it slowly to preserve the bubbles. Give the mixture one gentle stir with a long spoon to combine everything without losing the carbonation. For a beautiful presentation, garnish your drink with a few extra blueberries and a fresh sprig of mint. Your delicious blueberry mojito is now ready to be enjoyed.
