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 ↓
White Cake with Filling
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.
Make the cake
Preheat the oven to 350°F (175°C).
Beat the egg whites until stiff peaks form.
Cream together the sugar and butter until light and fluffy.
Add the milk and mix well.
Sift the flour with the baking powder and gradually add to the mixture.
Add flavoring to taste and mix until smooth.
Divide the batter into three greased cake pans and bake until golden.
Make the filling
For the filling, beat the 2 egg whites until stiff.
Boil 1 cup of sugar in ½ cup of boiling water until it threads.
Pour the hot syrup over the beaten egg whites and whip until smooth.
Fold in the grated pineapple.
Assemble
Once the cake layers are cool, spread the filling between the layers.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they add lift and a light, airy structure to the cake and filling.
- Butter
- Creamed with sugar to trap air, giving the cake a tender, fine crumb and rich flavor.
- Sugar
- Sweetens the cake and, boiled into syrup, sets the texture of the fluffy filling.
- All-purpose flour
- Forms the main structure of the cake once its proteins set in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Milk
- Adds moisture and helps form a smooth batter that bakes into a tender cake.
The step that matters
Boil the sugar syrup to the threading stage. Syrup that is undercooked will not set the whipped egg whites into a stable, fluffy filling, while overcooked syrup turns the filling hard and grainy as it cools.
Swap the pineapple
How well each one fits the dish's main ingredients (egg, sugar, butter, milk, flour):
- Vanillafits better
- Raisinfits better
- Figfits better
- Pineapplethe original
Fit is the average pairing score against egg, sugar, butter, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
