Pork Porterhouse with Sautéed Quince, Apples, and Potatoes

This is not your mild-mannered pork chop! The pork porterhouse is two cuts of meat in one—just like its better-known cousin the beef porterhouse. From the short loin of the pig, the pork porterhouse (porkerhouse?) consists of the soft, luscious tenderloin on one side of the bone and the meatier loin on the other. The classic American accompaniment to pork is, of course, apples. But in place of the traditional applesauce, I like to serve these hefty chops with the time-honored duo of apples and potatoes. Called deux pommes, or two apples—one from a tree and one from the earth—the two are sautéed together until crispy and golden brown. To show off more of fall’s cornucopia, I’ve added quince, “Eve’s apple,” to the mix. Slathering the chops with quince jam (membrillo in Spanish cuisine, cotognata in Italian) is a sophisticated nod back to that applesauce. Be sure to cut the quince, apples, and potatoes into similar-sized pieces, so when they’re cooked they all look the same. The mystery is part of the fun; there’s no telling which bite will be which pomme.
