Why it works: Milk and flour 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 ↓
Cream Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the crusts
Preheat the oven to 400°F (200°C).
Roll out the bottom pie crust and place it in a pie plate.
Roll out the top pie crust and set aside.
Place small wedges of dough between the crusts to prevent sticking.
Bake the crusts until golden brown.
Make the cream filling
In a saucepan, combine eggs, milk, flour, sugar, and lemon extract.
Cook over boiling water, stirring constantly, until thickened.
Assemble and serve
Pour the cream mixture into the baked bottom crust.
Top with the baked upper crust and serve.

Milk and flour 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
- Eggs
- Set and thicken the custard as they cook, giving the filling its body.
- Milk
- Forms the liquid base of the custard and adds creaminess.
- Flour
- Thickens the mixture as it heats, giving a smooth, sliceable filling.
The step that matters
Cook the filling over boiling water while stirring constantly. Egg and flour mixtures can curdle or form lumps if they heat unevenly or too fast. Constant stirring spreads heat evenly and keeps the proteins and starch dispersed, so the custard thickens smoothly.
Swap the lemon
How well each one fits the dish's main ingredients (egg, milk, flour, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against egg, milk, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
