I don't know what they do, but I'll sure be looking closer from now on - wherever I'm eating them.
Had leftover spare ribs last night, and will have a few more tonight. I needed to let those cook longer. Skin was splitting when I picked the rack up, but bones weren't exposed enough.
All in all, I won't be selling my pit on ebay/craig'slist/garage sale now. Going to think about labor day menu now.
