Doing a prime rib...have a few ?'s

SickEyeDiaz · August 2013

I have a 4 lb boneless prime rib ready to go for this afternoon. First time doing one on the BGE.

@t 250, app. how long will it take to get to medium rare?

About what should the internal temp be for medium rare? 120?

About how long should I let it rest after?

I was gonna do a reverse sear...should I do it right after it hits the right temp, or after it's been resting?

I thought about injecting it with some Au Jus...good idea or not necessary?

I want it nice and juicy...should I baste it once and a while or will it be fine without?

Thanks in advance friends and have a great day!

Never injected a rib roast, not sure it needs it.

Tie it to make it as round as possible, will cook evenly.

Temp in the egg (for me) is always about 250º.

15 minute rest is good if you pull 5º before target IT and do not sear.

If you plan to reverse sear, pull 10º before IT, rest while the egg heats, then sear, and you can serve almost immediately as it has already "rested". (I'm not a big believer of resting other than to let it finish cooking)

For reverse sear, I let the foiled roast rest, remove the setter and get the egg hot. takes about 5-10 minutes and then sear, depending on how much char you want.

Naked Whiz also has a simple way that I use. I take mine to 135 IT.

Did one last week covered in a paste of beef base, dijon, Lee & Perrins & a small amount of honey. Then gave a good coat of Cow Lick. Cooked indirect til 155. No need to sear. Perfect red/pink through out.

Skiddymarker is spot on. I do a reverse sear on the ends for folks that like their's a little more done. Worcester, Mustard, little s&p... Hard to mess up. Good luck. Pics please.
