Standing Rib Roast

Ricksegg

I am getting ready to cook a 6.5 pound standing rib roast.  I will be cooking it with the plate setter and the egg temperature at about 250 degrees.  Does anybody know about how long it takes to cook it until the roast is about 140 degrees?

get a good remote read thermometer, and when it hits 135 pull it out. my guess, at least a few hours

I cook prime rib with your set-up.  I generally see 25-30 mins/# til around 130*F on the meat thermo-so that will get you in the ballpark.  Use a drip pan on the platesetter with some spacers under the pan to collect the juices and not have them become burnt offerings. Spacers can be anything to create an air gap.  Enjoy-it will turn out great.

25 minutes will get you close but what it is really about is the cross-section of meat in either direction. If you have a narrow end and the roast is approximately the same length and width you will go 25 minutes. If it's a thicker roast (closer to the 6th vertebrae?) it will be more narrow in the other dimension it will take a bit less time.
