Yep... 2 times Buccs is correct. Cook it bone in and don't worry about "sealing" it. Meat seals itself once the exposed surface reaches about 150F, which happens very fast. It's also the reason why you get a smoke ring around the outside of any meat. The better smoke rings are formed through the smoke penetrating at a lower temperature for a longer time.
For a first timer using a kettle you dont need to worry about a forward or reverse sear. Put it in at 350F indirect. Put the lid on and leave it alone for at least an hour.
If you want to monitor the IT, use a Maverick ET732, but it's not really necessary.
You will find that the lamb has coloured up really well in that hour.
Here's ome of my progress shots on my Performer. This was a first time smoke on that unit.
That might be a little rare at the bone for you, but me and Frank Sacco like 'em Pink on the inside... for very different reasons. Not sure how you swing...:shocked:
But that aside, get the IT to about 120 - 125 and rest that 40 mins. That part is critical as lamb really does spill it's guts moisture wise if you slice it too soon.
As you can see, the colour is perfect on this lamb.. no searing at all.
Thanks for the PM.
Enjoy!
Cheers!
