Low-n-slo. I like a pit temp of 225° until it's within a few degrees of your target temp. Then rest a few minutes whilst ramping up the smoker or grill and give it a short sear to crisp up the crust.
The primes I have done, was just low and slow till about 135 to 140. I never have taken them off the smoker and crusted them over a hot bed of coals or sliced and crusted over a hot bed of coals. Someone here the other day posted of one crusted over after smoking.
What has worked for me on the Rec Tec
-Tie it up about every inch or so to make uniform
-Cook at 250* until internal of 135*
-Let rest at least 20 min tented, temp will rise about 5*
~Can alway pull around 125 let rest for at least 10 min then sear over high heat until 135*
Okay I’ve got a plan. Rubbed with some Savannah Style Hickory Smoked Beef Rub after rubbing on some garlic infused EVOO. Letting it soak it up tonight. Going on tomorrow at 260-265 until an IT of 130, then pull it off, crank up Joe and get a good sear. Rub has smoked paprika, chili powder, cane sugar, garlic powder, hickory smoked salt coarse black pepper , cumin, coriander, parsley and oregano.
