Why it works: Butter and milk 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 crust
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and sugar.
Add the eggs and mix well.
Stir in the milk.
Sift the flour and baking powder together.
Add the sifted mixture to the batter.
Divide the batter between two pie tins.
Bake until golden.
Make the filling
For the filling, boil 1 pint of milk.
Take out enough milk to wet ½ cup flour, then mix the flour with the milk.
Add the mixture to the boiling milk.
Stir in ⅔ cup sugar and the egg yolks.
Boil for 3 minutes.
Once cooled, flavor with lemon or vanilla.
Spread the filling between the baked pie crusts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the crust and thickens the filling as its starch swells with heat.
- Baking powder
- Releases gas in the batter, helping the crust rise and turn light.
- Eggs
- Add structure and richness to the crust batter as they set during baking.
- Butter
- Adds fat that tenderizes the crust and carries flavor.
- Sugar
- Sweetens the crust and filling and helps the crust brown.
- Milk
- Provides moisture to the batter and forms the base of the custard filling.
The step that matters
Boil the filling while stirring. The custard thickens as flour starch swells and the egg yolks set with heat. Keep stirring to prevent lumps or scrambling, and boil long enough for the starch to thicken fully.
