Beef Back Ribs are different than Short Ribs. Short Ribs are the best, Chuck Ribs are second if I'm smoking ribs.
I cook Back Ribs with the 3-2-1 method. I rub down with Yellow Mustard. Season with Lawry's Season Salt, course black pepper, garlic powder, onion powder.
Smoke 225 degrees over Post Oak wood indirect heat for about 3 hours, spray ribs with apple juice.
After 3 hours wrap ribs in foil or butcher paper with squeeze Parkay butter, brown sugar, apple juice, Tiger Sauce and go another 2 hours at 225 degrees.
After 2 hours in the smoker wrapped, unwrap the ribs. I like to dust them again with some rub and then cook ribs for another hour.
