Why it works: Milk and butter 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 ↓
One Egg 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the custard
In a mixing bowl, combine sugar, egg, sweet milk, salt, melted butter, and lemon extract, and mix well until smooth.
Pour the mixture into the pie crust.
Bake
Bake for 30-35 minutes or until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set as the custard bakes, giving the pie its firm body.
- Sugar
- Adds sweetness and helps soften the set custard texture.
- Sweet milk
- Provides the liquid base that bakes into the custard.
- Melted butter
- Adds fat for richness and a smoother, tender custard.
The step that matters
Bake until set. Egg proteins firm as they heat, so the custard needs to be baked until just set. Pulling it too early leaves a runny center, while overbaking can make it weep or turn grainy.
