This might seem like a simple recipe but when I was younger, I had no idea how to keep my fruit from going bad. The trick is to use lemon or lime juice. This helps prevent the oxidization that occurs when the cut fruit is exposed to air. The citric acid in the juice keeps your fruit fresher longer. I prefer lime over lemon, but both will work. Hope this helps make your summer parties last longer. Comment with any tips you might have that I can share with everyone.
