The 3 - 2 - 1 method is very easy to do. What I do is marinate my ribs, I do a 24 to 36 marinade, then rinse them off, dry them off, apply my glue for the Rub, which is Honey, then my Rub, which varies from time to time. I then wrap the rubbed ribs in Plastic wrap and into the fridge they go overnight. The next day I remove the plastic wrap, apply more Rub, then let rest while I get my smoker setup and warmed up, this process takes me about 30 to 40 minutes.
When I foil them, I add some of my Spritz I have in my spray bottle, in that is 70 to 80% Apple Juice, 15% Rum and 5% Apple Cider Vinegar and a couple shakes of Tabasco sauce. The last hour, I put them in the 225 degree smoker, no smoke, about 20 minutes before the are done I add sauce, if I want to.
These ribs I make, are better than anything you find at competition rib cooks even.
Notice I gave you no marinades or tastes, that is because you have find your own, what I like may and probably you will not like. Thousands of marinade recipes out there, find one you like.
