Don't throw out the cucumber juice! Instead, make a glass of Cucumber Lime/Lemon-Ade! I got this idea from something similar served at the Whole Earth Festival in Davis. Combine 1 part cucumber juice with 2 parts water (still, or sparking if you are in a festive mood) and add lime or lemon juice and sugar to taste. It is quick, tasty, and a good way to get some extra nutrients and hydration.
