Eating watermelon with salt is to enhance the sweetness of the watermelon.

Well it's not really "enhancing" but with the saltiness of the salt, it brings out the sweetness in the watermelon.

You can try eating plan watermelon, see how it taste like, and then sprinkle it with just a little bit of salt and try the difference! :)

It's the same concept when you try to make soup or savory stew, sometimes I add a little sugar to give it more depth.

sounds awful. something sweet with salt?
reminds me when a friend tricked me into eating spoonful of salt and sugar in 50/50 ratio. the most horrible thing you are going to taste.

A little bit of salt make some contrast with the sweetness.

I know some Japanese people eat watermelon with salt while I do not.

I can not imagine the taste of watermelon with white cheese.

I could never imagine salt and watermelon.

Recently, I encountered a new angle to this.

There was a paper offering recommendations for avoiding heat stroke, and one of them was that a bit of salt on water melon helped to keep you hydrated more than it would without the salt. The whole water, sugar, and sodium thing.

Not that I would actually eat it that way normally, but I suppose it wouldn`t hurt if you didn`t have access to a sports type drink but did have a watermelon and needed good hydration.

White bread with watermelon? O_o Whaaaat?

Why not leave the poor watermelon alone guys? Eat it plain as nature intended?
