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 ↓

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.
Prepare
Preheat the oven to 350°F (175°C).
Beat the eggs for a few minutes.
Make the filling
Stir in the butter, sugar, and milk.
Add the pineapple and its juice, mixing well.
Bake
Pour the mixture into a pie crust and bake immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the filling into a firm, sliceable custard as it bakes.
- Sugar
- Adds sweetness and helps give the filling its smooth, tender texture.
- Sweet milk
- Provides the liquid base that the eggs set into a custard.
- Butter
- Adds fat for richness and a smoother mouthfeel in the filling.
- Pineapple
- Contributes fruit flavor, moisture, and a bright acidity to the filling.
The step that matters
Bake immediately after pouring. Egg-based fillings can separate or thin if left standing, and a wet filling sitting in the raw crust can make the base soggy. Baking right away sets the custard while its texture is still even.

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