Be careful with that Butcher's injection, the sodium count is over 15,000mg and you could find yourself waking up at 3am with a dry-as-desert mouth.
I myself am trying something entirely new. I'm going to use onion soup mix, wine, onions and different seasoning. My BBQ Beef brisket is tasty but it's always the same thing. I'll inject low-sodium beef broth, Worcestershire and some other stuff..season with rub and then do a 5 hours in the smoker. From there, into a covered pan, add onions and return to cook until tender. I dunno, I'll figure it out and make it up. Chances are it'll come out great and then I'll never be able to reproduce the same results again.
But yeah dude, mix it up, have fun and let your ADD/OCD take you to new culinary heights! :thumb:
