This holds true for more than simply watermelons. A lot of naturally bitter veggies, like kale, cabbage, and Brussels sprouts, can be made better by adding salt, which balances their sharpness and brings out the desired qualities. Fruits that are more bitter than sweet, like cranberries and grapefruit, also benefit from a little salt to enhance their sugary flavor.

In addition, a light dusting of salt improves the texture and flavor of watermelon. This fruit is water-dense, so salt brings out the moisture to make every mouthful incredibly juicy and sweet. To get the best flavor, some experts suggest salting the slices and letting them sit for a few minutes before eating, so the magic can work.
