lotalota ;D ;D
 Your effort to get the perfect bloody Mary is to be admired ;D ;D
  Just a thought, instead of mixing the salt in the mix, how about taking a film can with shaker top and mixing up a batch of black/white. (coarse sea salt/coarse ground pepper)
Then just shake a little on top of drink as you go ;) ;)
You could use as food seasoning as well ;) ;)
Even add some Cayenne if you like your Mary with a attitude ;D ;D
