Sweet Potato Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potatoes
Steam or boil the sweet potatoes until done.
Peel and slice the potatoes.
Prepare a pie crust as you would for any other pie.
Assemble the pie
Layer half of the potato slices in the crust.
Add butter and 2 teaspoons of sugar, and spices if desired.
Add another layer of potato slices, then repeat with butter and sugar.
Cover with a top crust, fill with water, and ensure edges are well pressed together.
Bake in a 400°F (200°C) oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Form the soft, starchy filling that sets into the body of the pie.
- Butter
- Adds richness and moisture to the layered potato filling.
- Sugar
- Adds sweetness and helps the top crust brown in the oven.
The step that matters
Cover with a top crust, fill with water, and ensure edges are well pressed together.. Sealing the edges well keeps the filling inside during baking so the juices do not leak out and the pie holds its shape when sliced.
Swap the nutmeg
The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (sweet potato, butter, sugar):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Sagefits less well
Fit is the average pairing score against sweet potato, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
