Wasn't it a mustard/pickle juice mix? I used that on some short ribs and other beef cuts. It was nice. Nothing profound. Still messing around with it though.
It's just salt and acid. Ask how many comp guys use some form of acid. Citric acid is a big one. Acetic acid being another one. I think most pickles would have both... they do when I make them.
Yep. Didn't use as a spritz but mixed in with mustard for the slather. Then I sprinkled rub on afterwards. Made a great slather to bind the rub. I wouldn't say it was extra spectacular and game changing but was good.
