Step 1

Place the sugar and the water in a small saucepan over medium heat. Bring to a boil, stir, and then remove from the heat. Let cool completely (put it in the refrigerator to speed this along). This is the simple syrup.

Step 2

Remove the mint from the stems. Slice three of the limes into eight sections each.

Step 3

Place the mint and the lime sections into a large pitcher. Use a pestle, wooden spoon, or meat mallet to crush the mint leaves and the limes. Make sure to crush each of the lime sections until they release their juice.

Step 4

Add the blueberries and crush those, too. It doesn’t have to be perfect—some of the blueberries can still be whole.

Step 5

Pour in the rum and the simple syrup from step Stir to combine. Refrigerate until ready to serve.

Step 6

When ready to serve, stir the club soda into the pitcher. Cut the remaining lime into eight wedges.

Step 7

Place ice in each individual glass and pour the blueberry mojito mixture over the top.

Step 8

Garnish with a lime wedge and more mint. Serve immediately.
