I found a fun channel on YouTube from TosTinMan. He does videos on a bunch of different topics and one of the topics is grilling things up on his Weber Jumbo Joe.
Here is a video he did cooking prime rib roast on his Weber Jumbo Joe. The roast looks to weigh a little over three pounds. I’ll let you watch the video to see how he seasons things up. He grills indirect for about an hour, rotates the roast and goes for another hour.
I think it looks like it turned out very well! If you like the video make sure to suscribe to his channel!
