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
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
Combine sweet milk, sugar, egg yolks, butter, and flour in a saucepan.
Boil over medium heat, stirring constantly until thickened.
Pour thickened mixture into a pre‑baked pie shell.
Ice and bake
Whip egg whites until stiff peaks form and spread over the pie filling.
Place pie in a 350°F (175°C) oven for a few minutes until the icing browns.

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 and colour to the filling.
- Flour
- Helps thicken the filling so it sets smooth rather than runny.
- Egg whites
- Whipped into stiff peaks to form the meringue icing that browns in the oven.
- Sugar
- Sweetens the filling and helps the meringue stay glossy.
- Butter
- Adds richness and a smoother, softer texture to the filling.
The step that matters
Stirring the filling while it boils. Constant stirring over medium heat keeps the starch and egg yolks from scorching or lumping on the pan bottom, so the custard thickens evenly and smoothly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
