I am going to cook my first butt for my sons birthday party on Saturday. This will be my first long cook. Looking for any input as to what the best way is. Low and slow or nitro. Also what lump to use, I have some BGE, WGWW, B&B oak or Harris teeter. Also may try to stop at the orchard up the street to see if I can get a few peach tree chunks as they just trimmed some trees. I have seen where it is discussed to leave the butt in the fridge overnight uncovered to get tacky, why? The butt weighs 15 lbs any idea of how long it would take, the party is at noon Saturday and I won't be home until tomorrow afternoon. Thanks for the help.
