Couple of year back I found briskets at wally (select Excel brand) I don't remember the price but it was way cheap at the time so I bought 3. I prepped and cooked one and froze the other two. the one I cooked had funny black specks in and on the fat cap as did the other two. anyway it seemed to have cooked fine looked great , moist and tender. but tasted god awful like OLD OLD beef, not a good taste at all. :icon_sick I gave the other 2 to a neighbor told him how bad I thought they were and he should just feed them to his dog (I later found out he ate them):icon_shock1:
I have since then never bought the Excel brand and ALWAYS a "choice" and have not had a bad one since then.
OH, when I saw the black specks I was leery but the meat didn't feel slimy or have an "off" smell to it so I proceeded with the cook.
