A couple days ago I received an email from Cookshack and among other things it contained a recipe for injecting a pork butt. I'm curious about this. I've never injected a PB because it was my opinion that a PB is loaded with internal fat and collagen therefore it shouldn't need the extra moisture. Since the recipe contained only salt, sugar, vinegar and water it would add little flavor. What is the thinking here? Have I been missing something by not injecting? I'd be happy to give it a shot if there would be some significant gain that I am presently unaware of. Please comment. Thanks a bunch.
