My recommendations for using plowboys yardbird on ribs.
1- prep the ribs. Wash, pull membrane, rub it up. Plowboys Yardbird is very salt, so be careful to not put too much on it. I think a nice even light to medium coating of plowboys is best. Put ribs in the fridge.
2- get pit started. Cook at whatever temperature you are used too.
3- once pit is ready put ribs on the pit. You do not need to have the ribs rubbed over night. This does lead to a texture change in the meat if you the salt content is high in your rub. It leads to a "hammy" texture. I always prep my ribs, go get the pit ready. Once pit is ready then go into the smoker. That is enough time for the rub to get into the ribs.
4- cook until the ribs pass the bend test. This is the true form of being done. Not time or temperature. If you want to wrap you can, if you want to go nekkid you can. Whatever your preference is here.
