Hey, I tried the salt with the cowboy coffee this morning. My cowboy coffee has been inconsistent. Not in a bad way, but from day to day it comes out pretty darn good to great. Today with the salt (about three pinches to the pot) it came out great.
That may have been coincidental, but the other benefit seems to be that the salt helps settle the grounds out. I usually use the cold water trick, which settles out the majority of grounds, but I use a very coarse ground and there are always still a few "floaters" - the larger chunks of grind. This morning there were none.
