Don't Overdo the Salt
More salt isn't necessarily better.
A common mistake would be assuming that if a little salt helps, a lot must help even more.
That's not how food preparation works.
A heavily salted solution can make sweet pineapple taste unpleasantly salty and may draw too much moisture from the surface of the fruit.
The goal is simply a lightly salted soak.
You want the pineapple to remain sweet, juicy, and refreshing.
If you can clearly taste salt after preparing it, you've probably used more than you need.
