I will salt a particularly underripe watermelon because the flavor is better than the plain melon. But a good watermelon is preferable unsalted.
Yup I have salted watermelon since I was a child! My husband thinks it is gross and will bring it up now and then at a cookout. Sometimes there are others like me. (usually my family tho LOL) cant wait to try pepper on cantaloupe
Husband also thinks it’s weird that I put salt and PEPPER on corn on the cob.
Salt on cantaloupe, but not on watermelon. Dem’s da rules - sorry. 
Salt on watermelon and cantaloupe, definitely. I notice that neither my wife nor my kids have copied my habit, however.
Salt on watermelon is disgusting. Salt on apples is just as bad.
People who salt watermelon are probably the types who add salt to McDonald’s burgers and fries.
Agreed.
Southerner. Absolutely salt watermelon. Very common here. But not ubiquitous - plenty of people don’t. Never heard of putting sugar on watermelon until I was an adult.
Don’t eat any other types of melon so can’t comment there.
I love sweet & savory, but just plain salt doesn’t do it for me. And people salt apples, too? I have never heard of that. But apples eaten with a handful of salted nuts, sign me up! Or melon & prosciutto. Yum! Or salty cheese paired with fruit (usually preserves) on a cracker. Yes please.
Always.
On cantaloupe and melon, I’ve heard of, but not watermelon. I’ve tried it on the first two and just didn’t care for it.
It’s not a sweet / savory deal. Salt (well, table salt) isn’t savory of course. It actually makes it sweeter. Both by suppressing bitterness and a direct mechanism for sweetening.
Watermelon? Pass the salt. And no snarky comments, please.
Growing up salt on watermelon was common. I’ve put salt on watermelon as recently as yesterday. More often than not these days I just eat it plain.
Sugar on melons seems like overkill to me.
I’m from the south. Pass me that salt shaker. Definitely salting watermelon, canteloupe, honeydew. Also lemons, limes, grapefruit. I don’t tend to salt oranges or tangerines, but they’re in the minority here.
It’s a southern thing. Yes
Salt brightens the flavor of watermelon (never tried it on other melons). I’m not from the south and no one from my family is either. Learned it from my dad. I no longer put salt on my watermelons, however. If the melon is good and crisp and sweet, it doesn’t need enhancing. Plus, the less salt I eat, the better.
He’d really think it weird that South Asians tend to put lemon and cayenne pepper on corn on the cob (the best way to eat it, IMO).
I didn’t salt watermelon until a few years back, and now I think it’s far superior to do it that way.
This. Salt enhances flavors. Nobody poo-poos salted caramel.
My dad put salt on watermelon only. My mom salted other melons, excluding watermelon. Whatever works.
Another Southerner here. Mom taught me to salt watermelon if it “needed” it due to bland flavor. She also lightly salted grapefruit and let it stand for a few minutes before eating. Mom said this cut the acidity. I wasn’t sure that this was correct, chemically speaking, but I knew better than to argue with Mom. And she was right about the improved flavors. These two fruits are the only ones that Mom salted, though.
