Sweet Potato Pie

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.

Prepare the filling

  1. Beat the eggs until light.

  2. Add syrup, milk, and sweet potatoes to the eggs and mix well.

  3. In a separate bowl, combine sugar, cloves, nutmeg or mace, ginger, cinnamon, and salt.

  4. Add the dry mixture to the sweet potato mixture and stir until combined.

Bake

  1. Line a pie pan with flaky pastry and pour the mixture into the pan.

  2. Bake in a hot oven (400°F) for the first 8 to 10 minutes, then reduce the heat to moderate (350°F) and continue baking until the pie is firm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Bind the filling and set it into a firm, sliceable custard as it bakes.
Sweet potatoes
Provide the bulk, body and earthy flavour of the filling.
Sugar
Sweetens the filling and helps it brown lightly at the edges.
Sweet milk
Adds moisture and richness, loosening the filling so it bakes smooth.
Syrup
Adds sweetness and moisture while deepening the filling's flavour.

The step that matters

Bake until firm. Eggs set as they heat, so the pie must bake until the centre is firm, not just the edges. Stopping early leaves a runny filling, while overbaking can cause cracking or weeping. The initial hot oven starts the set, and the lower temperature finishes it gently.
