I love preparing duck, because nothing is wasted. Use the liver and make a deconstructed pate by sauteing shallot in butter; add the liver and mash, then add a little S&P. Served on baguette, this makes for an easy appetizer. After many less than optimal results with roasting duck, I finally learned that the secret to a really good crispy skin is boiling it before roasting. I also let it dry in the fridge for a couple of days before roasting. Save the broth, chill it, then skim off the fat that will rise to the surface and save for use in other recipes. Julia Child was right when she said, "Always save your duck fat." Once the broth is reduced, combine with veal stock, reduce more, & you will have a lovely sauce. The first time I boiled a duck, I didn't realize how out of control a hot slippery duck could be--sloshing hot greasy liquid all over my tiny kitchen. So the second time, I trussed the legs together, leaving the twine long, in order to have something to hold on to.
