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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
In a bowl, combine sugar, eggs, and flour, then beat until creamy.
Melt the butter, add it to the mixture, and beat again.
Stir in the milk and flavor with lemon or vanilla.
Bake
Pour the mixture into the pie crust and bake at 350°F (175°C) until set.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Set the custard into a sliceable structure as they cook.
- Sugar
- Adds sweetness and softens the texture of the filling.
- Flour
- Thickens the mixture and gives the filling body.
- Butter
- Adds richness and a smoother, silkier mouthfeel.
- Milk
- Supplies the liquid that the eggs set into a custard.
The step that matters
Bake until set. Eggs thicken as they heat, but overbaking makes the custard curdle and weep liquid. Pull the pie once the center barely wobbles, since it firms further as it cools.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, flour, butter, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against sugar, egg, flour, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
