This is our version of Choucroute Garnie, a classic French dish of sauerkraut ("choucroute" is French for sauerkraut) slowly braised with duck fat, onions, and spices in white wine and chicken stock. Smoked pork chops and sausages are nestled into the sauerkraut to cook. The sauerkraut's flavor mellows and absorbs the flavors of the spices, cooking liquid, and pork, and its texture turns meltingly tender. We've tossed in some apples for a little extra sweetness. For a German twist on this dish, try substituting an amber beer for the white wine. No matter how you make it, though, be sure to pass a pot of good mustard at the table.
