3 limes, quartered
1/3 c. sugar
4 tbsp. sweetened condensed milk
Place all ingredients in a blender or processer. Add 4 cups cold water and blend on high speed until limes are slightly chopped. Strain into a pitcher and then with the strainer still resting above the pitcher, slowly pour about 1 more cup of water through the strainer over the lime pieces to extract all the residual sugar and juice. Refreshing!
