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 Pies Without Eggs
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.
Prepare the pumpkin
Peel and cut the pumpkin into small pieces.
Boil the pumpkin pieces until thoroughly cooked.
Make the filling
In a bowl, mix the sugar, prepared pumpkin, flour, and milk together. Add spice to taste.
Pour the mixture into the pie crust.
Bake
Bake at 350°F (175°C) until the crust is golden and the filling is 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
- Pumpkin
- Provides the bulk, flavor and body of the filling.
- Flour
- Thickens the filling so it can set as it bakes.
- Milk
- Adds moisture and richness to the custard-like filling.
- Sugar
- Adds sweetness and helps balance the pumpkin's earthy flavor.
The step that matters
Baking until the filling is set. Pumpkin custard continues to firm as it cools, and the starch from the flour and proteins from the milk set with heat. Pulling it too early leaves a loose, runny filling, while overbaking can cause cracking or a watery texture.
Swap the pumpkin
How well each one fits the dish's main ingredients (sugar, flour, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Pumpkinthe original
Fit is the average pairing score against sugar, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
