Sweet Potato Pie

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

  1. Preheat the oven to 350°F (175°C).

  2. Prepare a rich pie crust and lay in slices of boiled sweet potato.

  3. Add thin slices of mellow apple on top.

  4. Spread thickly with sugar and butter, then add spices to taste.

  5. Cover with another crust and bake until golden.
