It is good! I followed PaulaG's advice and use the Memphis Style Back Ribs cooking method and the Outback Steakhouse rub instead for my ribs (because I had a big batch of those) and it's great!
I am in love with this sauce! It is wonderful. I used the rub from my Memphis Style Baby Back Ribs to rub same country style pork ribs, smoked them and the last hour of cooking basted them with this sauce. Not having the A-1 sauce I used barbecue sauce from a bottle. It cooks up quickly and like I said wonderful!
