When I lived (and suffered) in Texas, I loved BBQ. My father who still lives there is pretty up on BBQ skills.
He found out long ago a secret to the best places. Adkins BBQ spice.
I was traveling through DFW with a few bags once and the TSA lady asked what it was. I told her "Adkins" and she said that was the only stuff she ever uses.
Not meant as a TSA endorsement but a Texan one.
I rub the stuff all over the ribs and then vacuum bag over night. Excessive but my "trick". I used a rib rack to cook 6 baby backs at a time. I make a huge foil "tent" (closed) and put the ribs in the Traeger for 2 hours on medium, about 300 degrees I think. I use mesquite almost exclusively. Just my preference.
I am happy with non sauced ribs but the last few times I slathered with Stubbs original and opened the foil and put the Traeger on "smoke" for another hour.
I always do that last hour that way regardless of slathering or not.
Ask fawndog, GoGo or AFMotorsports how they come out.
For a party try taking a 10 pound+ brisket and dump a whole bag or more of the seasoning on top where the fat cap is. Smoke for 24 hours at about 200 or 250 degrees. The fat soaks through the meat and pulls the spices through. It turns out simply incredible!
