Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. 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 cooked pumpkin, egg, flour, sugar, milk, and salt until smooth.
Bake
Pour the mixture into a pie crust.
Bake for 30‑40 minutes or until set.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked pumpkin
- Provides the main flavor and moisture of the filling.
- Egg
- Sets during baking to give the filling its firm, sliceable structure.
- Flour
- Thickens the filling so it holds its shape when cut.
- Sugar
- Adds sweetness and balances the savory pumpkin flavor.
- Sweet milk
- Forms the liquid base that gives the filling its creamy, custard-like texture.
The step that matters
Bake until just set. Egg proteins firm as the filling heats, so underbaking leaves it runny while overbaking makes it curdle, weep, or crack. Check for a center that jiggles slightly rather than sloshes.
Swap the pumpkin
How well each one fits the dish's main ingredients (egg, flour, sugar, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Pumpkinthe original
Fit is the average pairing score against egg, flour, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
