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 Peach Pie
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.
Assemble the pie
Preheat the oven to 400°F (200°C).
Line a pie plate with the pie crust.
Fill the crust with halved peaches and sprinkle thickly with ½ cup sugar.
Cover with an upper crust, buttering the edge where it touches the lower crust.
Bake
Bake until golden brown.
Make the cream and finish
While the pie is still hot, lift the crust and pour in the cream mixture.
In a double boiler, heat the milk, then add the whipped egg whites, remaining sugar, and cornstarch.
Cook for 3 minutes, stirring until thickened, then cool completely before pouring into the pie.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pie crust
- Forms the container that holds the filling while it bakes.
- Peaches
- Provide the fruit filling and its juices, which add moisture and flavor.
- Sugar
- Adds sweetness and draws juice from the peaches to help form the filling.
- Milk
- Forms the liquid base of the cream that sets when heated and thickened.
- Egg whites
- Help the cream set and give it a light, airy structure when heated.
- Cornstarch
- Thickens the cream mixture as it heats, giving it a smooth, sliceable body.
The step that matters
Cooking the cream until thickened. Cornstarch only thickens once the mixture is hot enough to gelatinize its starch. Stopping early leaves the cream runny, so stir steadily over the double boiler until it thickens before cooling it.
Swap the peach
How well each one fits the dish's main ingredients (sugar, butter, milk, egg):
- Vanillafits better

- Peachthe original
Fit is the average pairing score against sugar, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
