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 ↓
Mock Cream Pie
Ingredients
Directions
Make the filling
In a kettle of water, boil the milk.
In a bowl, mix flour with a little of the milk to create a paste.
Add the flour paste, sugar, and well-beaten egg to the boiling milk.
Stir until thick, then remove from heat and let cool.
Bake and assemble
Bake 2 pie crusts.
Sprinkle flour between them to prevent sticking.
Fill the cooled crusts with the cream mixture flavored with lemon.
Optionally omit the top crust.
Cover with light frosting.
Brown quickly.

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
- Milk
- Forms the body of the custard filling once thickened.
- Egg
- Helps thicken and enrich the cream filling as it sets.
- Flour
- Thickens the milk into a stable, sliceable cream.
- Sugar
- Sweetens the filling and balances the flavor.
The step that matters
Stir until thick. Flour starch thickens only when the mixture is hot enough and stirred while it cooks. Stopping too early leaves a thin filling, and the egg can curdle if it is added to milk that is not kept moving.
Swap the lemon
How well each one fits the dish's main ingredients (milk, egg, sugar, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against milk, egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
