Salt makes pineapple taste even sweeter
It isn’t that the pineapple itself becomes sweeter, but it’s the way we process flavors. Common table salt can reduce the bitter taste of foods, so when added to pineapple, it reduces the bitterness of pineapple. When there’s no bitter signal going through to the brain, this means that it cannot suppress the sweet flavor. Hence the magical sweetness!
Today's version really, REALLY sucks- it doesn't have much of anything.
