BBQ is all about trial and error. Jeff makes the error part a very small percentage of your trials. Wash your ribs, dry thoroughly, use your nose to detect age, remove the membrane, then be liberal with your application of French's yellow mustard. Now buy Jeff's rub recipe, make a fresh batch each time, and apply evenly until you can't see any yellow and then...let the ribs set until there is a beautiful, glistening crust. The aroma will be wonderful. I don't rub, pat or otherwise disturb the rub, just insert your meat thermometer probe and gently place on your grate. These ribs will not need to be mopped as the crust of rub seals the meat. Just be sure to monitor your meat temp and ambient oven air temp at grate level carefully. Consistent success depends on keeping the air temp constant within a swing of about 15 degrees. Over a 5 to seven hour cook you can come real close to your ideal cooking temp average. One other note, my experience has shown the moisture content of the dark brown sugar is an important variable in Jeff's rub recipe. If you use a left over batch, the bite of the spices becomes pronounced rather than subtle. I watched the video and my take on all the brown sugar and mop is that you really won't taste the meat. Well BBQ'd pork is a delight when cooked low and slow. Not at all greasy and the aroma is clean, not unlike fresh fish when cooked. Enjoy your time at the smoker!
