Grace Jones Rub Grabber, LOL. 2/3 Part Molasses, 1/3 part Soy or Worchestershire Sauce, 1/3 Balsamic Vinegar
I made this both because I Liked the profile but when getting a crew of 3 or 4 newbies (sometimes old women) to make 30 to 70 briskets, they seem to like painting more than rubbing mustard on. lol. I have used coffee, WS and Molasses too. Thats old school wagon train stuff though.
