Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Pumpkin 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the filling
Preheat the oven to 350°F (175°C).
In a bowl, mix the boiled pumpkin, sugar, and flour.
Add the sweet milk and the beaten egg yolks to the mixture.
In a separate bowl, beat the egg whites until stiff peaks form, then fold them into the pumpkin mixture.
Melt the butter and stir it into the mixture.
Bake
Pour the filling into pie crusts and bake for about 45 minutes or until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard and whites, whipped to stiff peaks, add lift and a light texture.
- Boiled pumpkin
- Provides the bulk, moisture and flavor base of the filling.
- Sugar
- Sweetens the filling and contributes to browning at the edges.
- Flour
- Helps stabilize the filling so it sets into a sliceable texture.
- Sweet milk
- Adds liquid and richness that the eggs set into a custard.
- Butter
- Adds fat for richness and a smoother mouthfeel.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives lift, but overmixing or deflating them while folding makes the filling dense and loose. Fold gently, just until no white streaks remain, so the custard bakes light and sets evenly.
Swap the pumpkin
How well each one fits the dish's main ingredients (sugar, flour, egg, milk, butter):
- Vanillafits better
- Raisinfits better
- Figfits better
- Pumpkinthe original
Fit is the average pairing score against sugar, flour, egg, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
