I put a slightly over 1 pound flat cut brisket (bought clearanced, of course!) in the convection oven and when I removed it later it was so tough we couldn't eat it. I'd cooked it on low heat for quite awhile but apparently that wasn't enough. So I wrapped it up and stuck it in the fridge, figuring I'd deal with it later. Today is later. So here's what I have to work with:
I'm not sure if this will help but I sliced the meat and put it in my smallest slow cooker with a little beef broth and some seasoning. I'm going to cook it for a few hours on low and see if that tenderizes it some.
If it still isn't edible, I'll more than likely cut it into very small pieces and use it in our blackeye peas tomorrow. If it still isn't edible, its going in the trash. Blech!
