Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cream Pie
Ingredients
Directions
Make the filling
Heat the milk and butter in a saucepan until boiling.
In a bowl, beat the egg yolks with the sugar, flour, and flavoring until light.
Stir in the cold milk, then pour the mixture into the boiling milk, stirring constantly until thickened.
Assemble and serve
Pour the filling into the baked pie crust and spread the whipped egg whites on top.

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 filling as they set with heat.
- Flour
- Stabilises the custard so it thickens without becoming grainy.
- Butter
- Adds richness and a smooth, tender mouthfeel to the filling.
- Milk
- Forms the liquid base that thickens into the custard.
- White sugar
- Sweetens the filling and helps keep the yolks smooth.
The step that matters
Stirring the filling as it thickens. Egg yolks can curdle or scramble if they overheat in contact with hot milk. Stirring constantly spreads the heat evenly so the custard thickens smoothly.
