Never tried salt, but I have had bacon flavored coffee, and it seems to me like a lot of the flavor of bacon is salt, idk… bacon makes pretty much everything taste better
A pinch of salt can lower the bitter taste of coffee, and is also good in dark cocoa. It also helps make grapefruit taste sweeter and If you are making veggie noodles (turnips make great veggie noodles) soaking the raw noodles in a little kosher salt/water can take the bitter flavor out so they taste more like pasta noodles when they are cooked.
The night before my wedding I had stayed at my folks place. In the morning I was making a coffee and my mum asked if I was nervous. I said, nah not really.
Took a sip of my coffee and I had put salt in instead of sugar.
Putting salt in coffee is relatively common. Put a very small sprinkle in shitty coffee and it makes it a lot more tolerable. Think bad waiting room coffee etc.
