Once again from the freezer, a cut of meat that I'm not familiar with. It was marked: Brisket.
I'm familiar with brisket, but this was not a brisket shape (point or flat), and it had the ribs running through it. Whatever! It looked like it needed a low and slow cook. I coated it in turbinado sugar and paprika, garlic and onion powder, and black pepper. It mellowed in the refrigerator overnight.
The following morning, it went on to a 300f fire. The temperature hovered between 250f and 290f during the entire cook.
Eight hours later, I literally stuck a fork in it to find out if it was done. If you can twist a fork in a tough cut and have the meat pull away, it's time to set the table.
What meat there was shredded easily, but this cut (some brisket over some ribs) was mostly fat, connective bits, and bones.
