JosephB and I were just talking last night about what a huge difference grinding your own meat can make. Really, I think this is one element that can't be over estimated -- especially if the meat is ground a relatively short time before it is cooked. I imagine it has something to do with the fact that freshly ground meat is significantly less oxidized than ground meat that has sat around for a while. I would add that one must eat a hamburger rare, or no more cooked than medium rare, to appreciate the added value of freshly ground meat. I agree, but some do not. That is open to the individual in this club.
