Duck Fat Green Garlic Homefries
The recipe is the easy part, finding duck skin is a little more challenging. 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).
If you can't find green garlic, regular onions, leeks, shallots, or scallions are all fine substitutes.
