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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness to the filling.
- Egg whites
- Whip into a stiff foam that forms the meringue topping.
- Cornstarch
- Thickens the filling as it cooks in the hot milk.
- Flour
- Adds extra thickening to help the filling set smoothly.
- Sugar
- Sweetens the filling and helps stabilize the meringue.
The step that matters
Cooking the filling in boiling milk. Starch granules only thicken fully once the mixture reaches a boil, so stir constantly to prevent lumps and scorching on the bottom of the pan.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, flour, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
