Not surprisingly, many of our oldest holiday traditions are actually rooted in waste reduction, thrift, and preservation. When buying a whole animal—like your holiday bird—consider how to make the most of it. Turkey or duck soup, for example, can be made from the bird’s carcass, and homemade gravy can be made from the animal’s giblets. Age-old recipes for stocks, soups, and sauces are often creative ways to re-use otherwise underutilized ingredients. Consider going to your local farmers’ market and asking the farmer directly for his or her “ugly” produce—it might be cheaper, and make for an awesome homemade jam or pie.
