Basil Limeade Concentrate recipe:

Ingredients

7 limes (reserve 1 for juice)
1.25 cups basil (packed)
4 cups simple syrup

Cut 6 limes into fourths and throw them (skin and all) into a blender. Add the juice of the seventh lime, then the basil leaves. Pour in the simple syrup, and blend until coarsely chopped but not puréed. I ran my Vitamix on the four setting for about five seconds. Let the mixture infuse for twenty minutes, then strain it into a pitcher, making about 4 cups of concentrate.
