Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Cream Pies
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the crust
Preheat the oven to 400°F (200°C).
Beat the egg whites to a stiff froth.
Beat the egg yolks and add the sugar.
Sift the flour with the baking soda and cream of tartar.
Add the sifted flour mixture to the yolk mixture.
Fold in the beaten egg whites gently.
Pour the batter into four pie tins.
Bake until golden.
Make the custard
Cook the milk in a double boiler for the custard.
Mix the cornstarch with a little milk.
Add the cornstarch mixture to the boiling milk.
Beat the eggs and sugar.
Stir the mixture into the milk.
Flavor the custard to taste.
Let the custard cool.
Assemble
Spread the cooled custard between two layers of pie crust.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift, and yolks add richness and structure to the batter.
- Flour
- Provides the structure that holds the baked crust layers together.
- Sugar
- Adds sweetness and helps the batter and custard brown and set.
- Baking soda
- Reacts with the cream of tartar to produce gas that lifts the batter.
- Cream of tartar
- Acidifies the batter so the baking soda reacts and helps keep the whites stable.
- Cornstarch
- Thickens the milk so the custard sets into a smooth, spreadable filling.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air bubbles in the whites intact; stirring or deflating them makes the crust dense and less light.
