I was watching Throwdown with Bobby Flay last night and while he did the most un-orthodox version of ribs, the guy he was going against did a true smoked spare ribs. During the preparation, the competitor mixed the rub with a liquid (don't remember what it was) to make almost a thin paste before applying it to the ribs. Said the liquid penetrates far more than the rub alone. i've always just put the rub on dry but has anyone tried liquifying it? it makes sense with that the liquid would penetrate more, but i'm wondering if it would burn like if you put the mopping sauce on too early. any suggestions of what liquid to add to the dry rub?
