Sweet Potato Pie

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

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

Assemble the pie

  1. Slice the parboiled sweet potatoes very thin and place them in a deep pie dish lined with pie crust.

  2. Sprinkle the potatoes with allspice, ginger, cloves, and nutmeg.

  3. Scatter small pieces of butter over the potatoes.

  4. Pour the sugar, molasses, and cream over the pie.

  5. Dust the top sparingly with flour and cover with hot water.

Bake

  1. Add the upper crust and bake for 45-50 minutes.

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

What each ingredient does

Sweet potatoes
Form the bulk of the filling and set into a soft, tender custard-like body as they bake.
Molasses
Adds dark color, deep sweetness and a rich, slightly bitter flavor.
Cream
Adds fat and moisture, giving the filling a smooth, rich texture.
Sugar
Adds sweetness and helps the filling brown lightly at the edges.
Butter
Adds fat and richness, melting through the filling as it bakes.

The step that matters

Slicing the sweet potatoes very thin. Thin, evenly sized slices cook through at the same rate as the custard sets. Thick pieces stay firm or hard in the centre while the outside overbakes.

Swap the sweet potato

Fit is the average pairing score against allspice, ginger, clove, nutmeg, butter, sugar, molasses. Candidates are from the same food group and used in at least 100 recipes.
