essentially, my childhood obsession with slushies just helped to prepare me for a neverending thirst for frozen drinks as an adult. 

frozen blueberry mojitos (makes 2)

2 cups blueberries (fresh or frozen)
1 1/2 cups ice ( if using frozen berries, decrease to 3/4 cup ice)
juice of 2 limes (about 4 tablespoons)
4 oz white rum
1/2 cup simple syrup 
10 mint leaves

add mint, lime juice and simple syrup to a blender and pulse until smooth ( big chunks of mint aren’t fun to drink, so try to avoid those) 

combine the berries, rum and ice with the mint mixture and blend until smooth

serve in a glass with a sprig of mint as a garnish
