Having trouble picking a watermelon?

Sorry I can’t help you with that as I haven’t mastered the art of watermelon picking myself, but I can tell you what I do when I cut open a watermelon and discover that it is not so sweet. I pour a can of 7UP or Sprite (or ginger ale in a pinch) over the sliced melon and chill the melon. The soda imparts a sweetness to the watermelon and adds a very subtle lemon-lime (or ginger) flavor to the melon.
