Why it works: Butter and milk 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 Custard Pie
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Line pie pans with rich pastry.
Make the filling
In a bowl, combine stewed pumpkin, grated nutmeg, flour, sugar, melted butter, beaten egg yolks, and milk.
Fold in the beaten egg whites last.
Fill the prepared pie pans with the mixture.
Bake
Bake the custards for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set the custard, giving it structure as it bakes.
- Milk
- Provides liquid that gives the custard its smooth, tender body.
- Stewed pumpkin
- Adds moisture, body and the main flavour of the filling.
- Sugar
- Sweetens the custard and balances the eggs and pumpkin.
- Flour
- Thickens the filling and helps it hold together when set.
- Melted butter
- Adds fat for richness and a softer, more tender texture.
The step that matters
Fold in the beaten egg whites last. Egg whites added gently at the end keep some air in the filling. Overbeating or overheating the eggs can make a custard curdle or weep, so bake gently until just set.
Swap the pumpkin
How well each one fits the dish's main ingredients (nutmeg, flour, sugar, butter, egg, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Pumpkinthe original
Fit is the average pairing score against nutmeg, flour, sugar, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
