I am pretty sure I am doing an 8.5lb prime rib on friday for a birthday gathering of mines and my wife's stepdad. I will be using an ecb with some of the mods done on it. Last time I used it my temp was around the 220 range, but all the other times the temp would be anywhere from 230 to 300 at times. I have done research and have found it takes 30 mins to a hour per pound to cook. We will be eating probably around 630pm or 7pm.
How long do you guys think it will take to cook it? I am not sure how everyone who will be attending likes their meat done, so I am gonna shoot for medium doneness. Has anyone done one in an ecb before? any tips for me besides overcooking it? The prime rib didn't come out of my pocket so I don't want to mess it up.
Man I hope i get my sfb for my chargriller for my b-day.
