This recipe for choucroute loaf, vaguely Alsatian in its addition of smoked ham, apples, mustard and caraway to the usual mixture of ground chuck, veal and pork, makes astonishing meatloaf and terrific Sunday lunch sandwiches afterward Paired with sauerkraut, the dish winks at real choucroute and in some ways is even more delicious For finicky kids, provide a side dish of mashed potatoes.
