Guess what?!? Those are pig bladders blown up to the size of basketballs. But you know what's even better? There's a whole chicken in there! Yup, this preparation is considered quite wonderful by the French. You place a whole chicken inside the pig bladder and then roast the whole concotion. Then we place each bladder into a copper pot and whisk it out to the client for their viewing pleasure. The bladder is then popped tableside and the chicken revealed. Fancy huh?
