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 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 pie layers
Preheat the oven to 350°F (175°C).
Beat the egg whites and yolks separately until stiff.
Add the sugar to the beaten egg whites.
Fold in the sifted flour, baking soda, and cream of tartar.
Pour the mixture into two pie tins.
Bake until golden.
Make the custard
Heat the milk in a dish placed in hot water.
Rub the cornstarch smoothly with a little milk.
Add the eggs and sugar.
Stir into the hot milk.
Flavor the custard to taste.
Let it cool.
Assemble
Spread the cooled custard between the 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
- Flour
- Gives the baked layers structure so they hold together under the custard.
- Sugar
- Sweetens the pie and helps the beaten egg whites hold their foam.
- Eggs
- Whites trap air for lift, while yolks add richness and help the custard set.
- Baking soda
- Reacts with the acid in the batter to release gas and lighten the layers.
- Milk
- Forms the liquid base of the custard and adds richness.
- Cornstarch
- Thickens the custard as it heats so it can be spread.
The step that matters
Stir the egg and sugar mixture into the hot milk. Eggs can scramble when they meet very hot liquid. Cornstarch needs heat to thicken, but the custard should be stirred steadily so the eggs cook smoothly into a silky texture.
“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.
