My grandmother (who really was a good cook) once accidentally put salt in a dessert she made instead of sugar. I can’t remember what the dessert was, she made lots of them, but I remember biting into it.
My GF in college made me a coffee and put in salt instead of sugar. Three Spoons Full!!! I spit it across the room…
You wouldn’t think it was good, but Tibetans drink salty, buttery tea and it’s delicious.

I only had it with yak butter once, but it didn’t make a huge difference to my Western taste buds.
