Hi Norm!
Just wanted to let you know, it has to be the Meat.
I just did another one a couple days ago, and I did it just like I did the two in my Step by Step Index:
I did the other two at 133° for 21 hours and 133° for 22 hours & they were both Fork Tender & Perfect.
The one I did the other day, I did at 133° for 21 hours, and I could cut it with my fork, but only if I exerted about 100 pounds of pressure on the fork.
The taste was Great, just like the other two, but this one was tough.
So I'll be trying a few more hours myself next time to see what happens.
Just wanted to let you know,
Bear
