I smoked a 5.5lb bone in rib roast today.
Covered in dijon mustard and rubbed with Costco Prime Rib dry rub. I also added some thyme and garlic powder for good measure.
Took about four hours at 235F. I pulled it at 126 and it came up to 134 after resting. This is the 2nd I've done and I'm always surprised at how much smoke it picks up. Not overwhelming but it's noticeable. Quite tasty.
