I'm just guessing, but I bet there's some old French kitchen expression that roughly translates to, "Hey, it has crispy, fried duck skin crumbled over the top, how bad can it be?" This video recipe for duck fat homefries is perfect when you find yourself in possession of this highly coveted ingredient.
The recipe is the easy part, finding duck skin is a little more challenging. The easiest method of attainment is to know a duck hunter. They can hook you up faster than you can say, "Nice Elmer Fudd hat." If that's not an option, try and make friends with line cooks who work at restaurants that serve duck. They can make it happen, and it will probably only cost you a couple draft beers.
Finally, you can go to a butcher that sells whole ducks, and have him break one down for you. Tell them you'd like two nicely trimmed breasts, two leg quarters, and all the excess skin from the rest of the carcass. They will smile knowingly, and say no problem (for extra credit, ask for the bones, which you can roast and make a killer stock).
Once you have your precious skin, the recipe is a breeze. If you can find green garlic, it's very nice in this, but regular onions, leeks, shallots, scallions, etc. are a fine substitute. These potatoes would sure make a memorable side dish to a seared, sous vide duck breast, or how about as a plate-mate to a creamy goat cheese omelet? By the way, I'm much hungrier now than I was when I started this post. Enjoy!
