I just pulled out three slabs of brisket from my new MES30 after 12 hours at 250 degrees and with IT at 189. I wrapped them in foil to cool. I'm not sure if tender enough. One felt tender with the "fork test". I'm not sure about the other two. Attached are pictures.
I am thinking of putting them wrapped in foil in a standard oven for a couple more hours since I don't need them until much later. Should I do it?
