Good Morning. #49 of the "60 uses of salt says", Use salt in your coffee grounds when brewing.
I do like the South American Citizens do, I mix in a little cocoa along with the salt. The amount of each? Beauty is in the eye of the beholder. just try a little of each & see for yourself if it satisfy's you. I hope this will help you. Have a nice day young lady, ~Chef Dunask.
