Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Cream Pie
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Separate the egg yolks from the whites.
In a double boiler, beat the yolks lightly and add milk, sugar, butter, and salt.
Moisten the cornstarch and whip it into the hot mixture, stirring constantly.
Boil for 5 minutes, then add vanilla.
Top and bake
Beat the egg whites to stiff peaks and gradually add 1 tablespoon of powdered sugar.
Pour the filling into a baked pie crust and spread the egg whites smoothly on top.
Brown carefully 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
- Eggs
- Yolks thicken the custard, and whipped whites form the light topping that browns.
- Cornstarch
- Starch thickens the milk mixture as it heats, giving the filling its body.
- Milk
- Forms the liquid base of the custard and sets into a creamy filling.
- Sugar
- Sweetens the filling and helps the meringue topping become stiff and glossy.
- Butter
- Adds richness and a smooth texture to the custard.
The step that matters
Boil the custard after adding cornstarch. Starch only thickens fully when it reaches a boil while being stirred constantly. Stopping early leaves the filling thin, and stirring too little can scorch or lump it.
