Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Kentucky 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
Make the pie crust and preheat the oven to 350°F (175°C).
Spread the crust with any kind of stewed fruit.
Make the filling
In a bowl, mix the butter, sugar, and egg yolks until well combined.
Fold in the beaten egg whites gently.
Pour the mixture over the fruit.
Bake and serve
Bake until golden brown.
Serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness, giving the filling a soft, smooth body.
- Sugar
- Sweetens the filling and helps it brown during baking.
- Eggs
- Set the filling as they cook and add structure, while whipped whites lighten the texture.
The step that matters
Fold in the beaten egg whites gently. Whipped egg whites hold air that gives the filling lightness. Stirring vigorously deflates them, leaving a denser, heavier result after baking.
