Could any girl who grew up in the 80's, watched the Karate Kid over and over and over again, and dreamed daily of Ralph Macchio while singing Cruel Summer resist making this drink? Yeah. I didn't think so.
adapted from 400 Blender Cocktails
2-4 Tbs. freshly squeezed lime juice
1/4 c. confectioners' sugar
4 oz. white, amber, or dark rum
6 ice cubes
Blend everything in the blender on high speed. (Start with the lesser amount of lime juice and add more to taste.) Pour into glass and serve. I garnished with a few banana slices.
