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 custard
In a saucepan, combine sweet milk, sugar, egg yolks, butter, and flour.
Boil the mixture over medium heat, stirring constantly until it thickens.
Fill and top the pie
Pour the thickened mixture into a pre‑baked pie shell.
Whip the egg whites until stiff peaks form and spread over the filling.
Brown and serve
Place the pie in a 350°F (175°C) oven for a few minutes until the icing begins to brown.

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 as they set with heat.
- Flour
- Thickens the milk mixture so the filling holds its shape when cut.
- Sugar
- Sweetens the filling and helps give the custard a smooth texture.
- Egg whites
- Whipped into a stiff meringue icing that browns lightly in the oven.
The step that matters
Boiling the custard while stirring constantly. Flour and egg yolks thicken only when the mixture reaches a boil and stays in motion. Stopping the stirring can scorch the base at the bottom of the pan or leave lumps, and undercooked starch and yolk will not set firmly as the filling cools.
