Don't have an egg. Still smoking on an old Weber kettle grill. But, I wanted to put this somewhere.
I was short most of the ingredients I use for a typical rib rub, so I winged it. Salt, pepper, little sugar, some paprika and cocoa powder. I thought the cocoa powder would kill it, but damn it was good. Best bark I've ever personally created.
Another observation. The megamart had Niman Ranch baby back ribs on super sale. They were cheaper than the Smithfield ribs, so it was a no-brainer. I smoked two racks of the Niman Ranch and one rack of Smithfield St Louis style ribs I already had. Same rub, same everything, just a longer smoke on the SL style ribs. It's difficult to describe how much better the hippie ribs were. I prefer baby backs, so not completely surprising, but it was more than just that. The Smithfield ribs lacked the depth and richness of the other ribs. They almost had an off taste to them, one that I only noticed when eating the two together. IDK, just thought it was interesting.
