Hi guys. I ordered some brisket from the butcher and my darling wife to be went down today to pick it up for me as I work nights and was sleeping. From looking at what she brought home the butcher has shown her a whole brisket and she's just said yeah that bit will do lol. Is this normal? Do I need to butterfly this? How long will this take to smoke? Meant to be cooking this tomorrow to eat at 7pm.
