Sweet Potato Pie

The November pie challenge in the Ravelry pie challenge group is family recipes. Lacking any handed-down family recipes for pies, I looked in a family cookbook, for a pie that could have been made--my mother-in-law Pauline's copy of the Prudence Penny Binding of the American Woman's Cookbook. Every family I knew had this cookbook--this edition's 1950s color illustrations are amazing.
