I was lucky enough to get a sample of Kosmo's Q beef injection. http://kosmosq.com/ This is my third brisket, and while the first two were tasty, they weren't as melt-in your-mouth tender as I would have liked. A lot of that had to do with my inexperience with briskets, but I wanted to try something new.. This injection put me over the top. 3 lb flat, 4 hours in the smoke and 2 more in foil.. Very happy with the results..
