I've never thought to smoke salt, but looks like you have!I put it on fine mesh screen pans spritz with alcohol. In my pitboss with smoke tube set on smoke mode (180°). Stir and spritz every 30 till I'm tired or like the color.
Alcohol used.
190 grain- for just the SMOKED salt
Tequila- for the lime batch
Bourbon- really couldn't tell the difference from the 190 on salt.
Bourbon- On pepper is awesome! Especially a high rye Bourbon!
