Juice apples, ginger root, Wonderful Seedless Lemons, and watermelon in a high-speed juicer.
Transfer juice into desired shot glasses, filling them up about ¾ full.
Top with POM Juice and drink right away, or chill in the refrigerator for up to 1 week.
Tip: Don't have a juicer? You can use a blender to combine all the ingredients, the strain the juice through a cheesecloth to filter out additional pulp.
