I'm New here and will be smoking a brisket I picked up today at Costco. The meat looks good, but I realized after I got hone Most people smoke brisket in the 8 plus pound range. the one I bought is only four. If I was following a step process that called for a 8Lb brisket, would it be ideal to Pressume the cooking time is cut in half? Thank in advance for any thoughts or suggestions!
