Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Philadelphia Butter 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.
Prepare
Preheat the oven to 350°F (175°C).
Cover a pie plate with the pie crust.
Make the filling
In a bowl, mix the softened butter, sugar, and flour until well combined.
Stir in the sweet cream until smooth.
Pour the mixture into the prepared pie crust.
Bake
Bake until the top is golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat, giving the filling a tender, creamy texture.
- Sugar
- Adds sweetness and helps the top brown as it bakes.
- Flour
- Gives the mixture body so it holds together rather than running thin.
- Sweet cream
- Adds moisture and richness, and smooths the filling.
- Pie crust
- Holds the filling in shape while it bakes.
The step that matters
Bake until the top is golden brown. Browning comes from sugars and milk proteins reacting with heat, so the colour shows when the top is ready. Pulling it too early leaves the surface pale and the centre underset, while baking too long can scorch the sugars and dry the filling.
“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.
