Ok here I go again. Tomorrow I plan on making a 3.5lb brisket flat and some spares. I would like to do the spares at the same time as well. The brisket has a good amount of fat on it so I'm thinking about doing a medium/high heat cook with the fat side down before foiling at 160*ish and then flipping it. Is trimming of the fat necessary? I read that some trim and some don't. Also do any of you marinade brisket? I was reading about a Dr pepper marinade what are your thoughts on this? Any other ideas or injections that you use? Thanks Vince
