No French Canadian Christmas Eve buffet would be complete without a slice of this rich meat pie, but tourtiere lovers eat this favorite year-round, hot or cold. Although pork is the most popular version, the dish can be made with beef, veal, or game meats. Fillings can include mashed potatoes, oats, flour, or cracker crumbs. It is often served with ketchup, gherkins, or pickled beets. If you're short on time, use a premade pie crust. Pie will keep for 4 days, refrigerated. May also be frozen, wrapped in plastic, for up to 3 months.
