1 tablespoon brown sugar
4 medium strawberries, hulled and diced
1/4 cup mint leaves, ripped
4 ounces mango rum
7.5 ounces Sprite
Using a mortar and pestle (or a bowl and spoon), mash together the strawberries, sugar, and mint.
Let sit for 5-10 minutes so the strawberries release juice.
Divide this mixture into two rocks glasses. Divide the rum and sprite between the glasses. Stir and add ice.
