Really great post Bob! Exactly how I do them and personally I think that Spares done in this fashion are better (and cheaper) than baby backs. I'll never forget the first time my wife looked at that big cryo packed slab of meat and bones and turned her nose up saying..."I only eat baby back ribs"... 6 hours later she agreed they were just as good (if not better) than any baby backs she had tried and best of all...cheaper. (She loves a deal.)
I'm slapping my forehead for not thinking of grinding the skirt and other trimmings!
I usually just throw them on and cook them until they are about the texture of jerky...love it, but would also like to try the meatball idea.
