Why it works: Sweet potato and nutmeg match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 414 recipes. Both carry linalool, which smells floral, citrus. The science ↓
Sweet Potato Pie
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the potatoes
Boil the sweet potatoes until soft.
Peel the boiled sweet potatoes.
Slice the potatoes.
Assemble the pie
Line a pie dish with the crust.
Place sliced potatoes on the bottom of the crust.
Add a generous layer of sugar, flour, and salt.
Layer more potatoes, more sugar, and bits of butter on top.
Pour in the milk or cream.
Flavor with nutmeg.
Bake
Bake in a slow oven at 300°F (150°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the main body and starchy, sweet filling that sets as the pie bakes.
- Flour
- Thickens the sugar and milk mixture so the filling holds its shape when sliced.
- Butter
- Adds richness and moisture, melting into the filling for a softer texture.
- Milk or cream
- Forms the custard base that sets with the egg-free starch and sweetens the filling.
- Sugar
- Sweetens the filling and helps brown the top during baking.
The step that matters
Bake in a slow oven until set. Baking at a low, steady 300°F lets the milk and starch set gently without curdling or boiling over. Pulling the pie too early leaves a runny filling, while overbaking can make it dry or cracked.
Swap the sweet potato
How well each one fits the dish's main ingredients (sugar, flour, butter, milk, nutmeg):
- Arrowrootfits about as well
- Sweet potatothe original
- Parsnipfits about as well
- Shallotfits less well
Fit is the average pairing score against sugar, flour, butter, milk, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
