We were at Costco today and they had a brisket flat that was about 3 1/3 lb. On Thursday, when I have plenty of time to sit around home, I'm going to put it in our 40" MES. I have a rub I love that I'll put on it. Any suggestions for cooking temp, internal temp, and a rough estimate of cooking time? I'm trying to attach pictures of both sides of the brisket, I hope it works.
