I use one of these
the OL got it for me for Christmas last year. Works like a MoFo!!
I'd advise against the KBouquet - it is guaranteed to stain the meat -
I wouldn't use it for a contest, as staining would obviously not be desireable in that situation. At home the staining won't hurt anything and might actually be helpful in that you'll get an indication of how effective you were at distributing the injection.
the injected and brined briskets win hands down
I think the benefits of putting your solution both in and around the meat (brisket, butt or whatever) is obvious. If you're gonna take the time to do one, augment it with the other.
Damn, I wanna cook now!!
