So, not my best cook. The flavor was fantastic but both were tough. The regular brisket flat doesn't surprise me. The corned beef was wrapped at 170 And started checking for tenderness at 200, at 203 it was still not there, at 205 still not there. Went to 207 and pulled it but still not probing tender. Does anyone have any thoughts? Should I have left it passed 207? Oh well, I won't cook another brisket flat, I'll stick to a full packer. But I will give the corned beef another try. Not every cook turns out perfect, these were my honest results. Oh, the cabbage was buttery and flavorful, everyone loved it
