Combine with chopped pork, garlic, and salt, and let hang out in the fridge while you deal with the feet.
OK. So, error the first: This recipe calls for a lot more shank than I bought. Mine are more up-to-the-ankle. No matter! We soldier on.
How to skin this? It's mostly bone. Some French chefs can slip their knives between skin and bone and remove it like a sock, but nuh-uh. Let's just take our time.
Yeah, that took about 15 minutes, and lot of effort. No lost fingers, though. Only three more to go.
To complete the farce, throw the pork and any odd foot scraps through the grinder.
Stuff each foot, and tie it up to keep everything together.
Bring chicken stock to a simmer with bay leaf and garlic cloves.
Lay out some cheesecloth, and roll up the feet. Then tie it up like a roast.
Place into the pot, and simmer for upwards of four hours.
Remove from the liquid, and unwrap. Don't discard that liquid! There's so much collagen in there, you've just made pork jello! Keep that around for your next noodle soup. It can be frozen. Anyway, place the feet in a roasting pan.
Still needs more flavor. Combine whole grain mustard with beer.
Roast, basting throughout, until the skin gets crispy. Note: The skin never got crispy.
Sigh, shrug your shoulders, and serve it anyway garnished with sea salt.
Tasting notes -- The flavors are good, but the texture was really, really soft. I suppose that's what it was supposed to be like, but it was personally unappealing. And rich. Really, really rich. I was looking for crispy skin, with an intense sausage bite. If I ever do this again, I might make a more chorizo-like sausage (or maybe merguez), and skip the poaching, going straight to a low-and-slow oven, like a barbecue. Live and learn, I suppose. On the plus side, I've got all that pork jello....
