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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
In a double boiler, combine milk, 3 tablespoons sugar, egg yolks, butter, and corn starch.
Cook until thick, stirring continuously.
Make the meringue
In a separate bowl, beat egg whites until stiff, gradually adding a little sugar.
Assemble and bake
Pour the thickened mixture into the pre-baked pie crust.
Top with the beaten egg whites.
Brown in a 400°F (200°C) oven.

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 a smooth, creamy texture.
- Corn starch
- Thickens the milk mixture as it cooks, giving the filling its body.
- Egg whites
- Whip into a stiff topping that sets and browns in the oven.
- Milk
- Forms the liquid base of the custard filling.
- Sugar
- Sweetens the filling and helps stabilise the beaten egg whites.
The step that matters
Cook the custard until thick. Cornstarch thickens only when the mixture reaches a full simmer and is stirred constantly. Stopping early leaves a runny filling, while overcooking can scorch the milk and eggs.
Swap the walnut
