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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
In a double boiler, combine milk, egg yolks, flour, and sugar.
Cook over simmering water, stirring until thickened.
Assemble and bake
Pour the filling into a pre-baked pie crust.
Beat the reserved egg whites until stiff peaks form and spread over the filling.
Place the pie in a 350°F (175°C) oven to brown the frosting.

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 liquid base of the custard filling.
- Egg yolks
- Thicken the custard as they cook and set the filling.
- Flour
- Stabilises the custard so it thickens smoothly without weeping.
- Sugar
- Sweetens the filling and balances the richness of the eggs and milk.
- Egg whites
- Whipped into stiff peaks to form a meringue topping that browns in the oven.
The step that matters
Cook the custard until thickened. Stirring over gentle simmering water keeps the egg yolks from scrambling while the starch and yolk proteins thicken the filling. Overheating can curdle the custard, and undercooking leaves it runny.
