From Cooking Light Magazine's July 2009 edition: "In this recipe, basil is crushed with sugar to release the oils. If you don't have a mortar and pestle, process the basil, sugar and about 1/4 cup of water in a food processor or blender." I am eager to serve this at my next party. The recipe doesn't indicate this, but I would personally place the strained lemonade into a pitcher and refrigerate until ready to serve. When having a party, it's always best to prepare ahead if possible!
