SOME people would just as soon ignore the culinary potential of the Carolina flying squirrel or the Waldoboro green neck rutabaga. To them, the creamy Hutterite soup bean is too obscure and the Tennessee fainting goat, which keels over when startled, sounds more like a sideshow act than the centerpiece of a barbecue.

But not Gary Paul Nabhan. He has spent most of the past four years compiling a list of endangered plants and animals that were once fairly commonplace in American kitchens but are now threatened, endangered or essentially extinct in the marketplace. He has set out to save them, which often involves urging people to eat them.

Mr. Nabhan’s list, 1,080 items and growing, forms the basis of his new book, an engaging journey through the nooks and crannies of American culinary history titled “Renewing America’s Food Traditions: Saving and Savoring the Continent’s Most Endangered Foods” (Chelsea Green Publishing, $35).

The book tells the stories of 93 ingredients both obscure (Ny’pa, a type of salt grass) and beloved (the Black Sphinx date), along with recipes that range from the accessible (Centennial pecan pie) to the challenging (whole pit-roasted Plains pronghorn antelope).
