I have a store that sells points separate from time to time. So far I think the points that have been separated from my Briskets after cooking,and then cooked more are better than the ones that were cooked by their selves. BUT what he is doing different is cooking both the flat,and point about the same amount of time. When you separate the point from the brisket the normal method is keep cooking the point a few more hours. So I have probably been overcooking the points I have bought separate. Thinking I need to render the fat out of it. I don't believe it's the quality of the meat,because I have bought a couple that were marbled beautifully and wasn't that impressed with how they turned out.
I think next time I get a point (or two) I will try following his method.
