For today's pie, I dug up something a little different. "Larrigan" literally translates to "moccasin," but larrigan pie is not made from shoes, it's made from vinegar, cornstarch, sugar and water and was eaten by lumberjacks. Ann Burkhardt included this recipe from the Forest History Center in her book A Cook's Tour of Minnesota along with some other recipes and food history relating to the woodsmen of northern Minnesota.
