A refreshing and vibrant cocktail perfect for warm evenings.
Juice the limes to extract all the fresh juice.
Roll the limes on the counter before juicing to get the most juice out of them.
Add the frozen blueberries, light rum, lime juice, simple syrup, and ice to the blender.
Layer the ingredients in the blender with the ice on top for smoother blending.
Blend the mixture until smooth and slushy.
Stop blending and stir if the mixture gets stuck to ensure even blending.
Pour the blended mixture into chilled glasses.
Garnish with a slice of lime or a few whole blueberries for an elegant presentation.
