To each of the four glasses, add 1/8 cup of fresh blueberries to with two tablespoons of sugar, use a muddler or the back of a spoon to gently muddle the blueberries until a thick, purple mixture forms.
Cut the limes into 8 thin wedges each (16 wedges total). Add 3 wedges to the bottom of each glass and set 4 aside for garnishing later. Add 3-4 mint leaves to the glass with the limes and use the muddle to gently crush them to release the flavor.
Using a glass or jigger, carefully pour 1.5 ounces of rum into each glass. Do not stir to avoid mixing the layers.
Carefully drop a few ice cubes into each glass, then pour the club soda over the ice until the glass is full, about 1/2 cup for each glass.
Garnish the drink with a lime wedge, mint leaves, and blueberries.
Serve immediately.
Notes
What’s The Best Rum For Mojitos? Traditionally, mojitos are made with a light rum. The specific rum is very subjective. Use a rum you like. I prefer using a rum with an 80 proof alcohol content and steer clear of higher-proof options like 151, which can overpower the drink.
For Smooth + Mellow Flavor: Dominican rums, like Brugal, Barceló, and Ron Matusalem, are typically clean, light, and slightly sweet, which pairs well with lime and mint in a mojito.
For Good Balance: Try Don Q Cristal (Puerto Rico), Bacardí Superior (Puerto Rico), or Havana Club 3 Años (Cuba). They often have subtle vanilla, oak, and tropical fruit notes, which can enhance a mojito without overpowering it.
Muddler: You’ll need a muddler for this recipe. If you don’t have one, use a long-handle wooden spoon.
Glasses: Grab four glasses that are wide enough and strong enough for you to use the muddler in. If you’d like and have the time, chill the glasses. I use Collins glasses because they’re nice and tall glass that shows off all the layers. A rocks glass, aka an old-fashioned glass, works well, too. If you muddle the mojito in a cocktail shaker rather than a glass, you can use a pretty, delicate martini glass, such as a coup glass.
Garnish: I like to use fresh blueberries on a pick and a wedge of lime. If you have a lot of mint, a sprig of it looks fantastic.
