I do something similar but I purposely want the Rosemary Garlic to develop a char for the taste. (I do the same thing with Tri-Tip ) Here are a few pics and recipe amounts of my last P.R. Roast.
First I make a Horseradish Sauce for the P.R.
Horseradish Sauce Recipe: (Tweaked from Chef John on Food Wishes)
1/2 cup sour cream or crème fraiche
1/4 to 1/2 teaspoon fresh lemon juice
pinch of cayenne
2 teaspoon thinly sliced chives. (I like to use Dill)
2 tablespoons extra hot (Atomic) pure horseradish (not horseradish sauce)
Next I make the Rosemary Garlic paste. (Amount may need to be tweaked depending on the size of the P.R.)
Rub Recipe: (From Larry of BEER-N-BBQ by Larry)
1/2 cup chopped fresh rosemary
3+ Tbsp crushed garlic
2 Tbsp salt
1 Tbsp black pepper
OO (Just enough to make it a paste)
I unwrapped the roast and trimmed off most of the hard fat.
I applied the rub (paste)
and then covered it with plastic wrap and let it sit on the counter for the next 4 hours to come up to room temperature.
I cooked mine on my kamado at 250 degrees but you can cook this in the oven as well.
After it reached an internal temperature of 124 degrees I pulled it off and covered it while the kamado got up to searing temps. (Note: many of my guests wanted it well done so the best I could talk them into was cooking to medium. If you want it to be medium rare then pull it at around 117 derees. It will continue cooking as it sits.)
Once the CI grate was nice and hot I put on the roast for 1 minute per side.
Here are some pics of me slicing it.
On the table on the Christmas platter.
And here it is plated with a Stone Brewing “
Pataskala Red X IPA” on the side. Both are waiting to be devoured.
Even though this was cooked to mostly medium it was still delicious. The rub / paste developed into a nice crust that was absolutely delicious.
