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 ↓
Lemon Cake
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).
Cream the butter and sugar together until light and fluffy.
Make the batter
Add the egg yolks, milk, lemon juice, and lemon rind; mix well.
In a separate bowl, beat the egg whites until stiff peaks form.
Gradually add the flour and whipped egg whites to the mixture, alternating between the two.
Bake
Pour the batter into two greased loaf pans.
Bake for about 30-40 minutes or until a toothpick inserted in the center comes out clean.

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
- Butter
- Creams with sugar to trap air and give a tender, rich crumb.
- Sugar
- Creaming with butter traps air for lift and adds sweetness and browning.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Eggs
- Add structure, moisture, and richness, and the whites lift the batter when whipped.
- Baking soda
- Reacts to produce gas that helps the cake rise.
- Cream of tartar
- Stabilizes the whipped egg whites so they hold their peaks.
The step that matters
Folding in the whipped egg whites. Whipped whites hold the air that lifts the cake. Adding flour and whites in alternating portions and mixing gently keeps that air from deflating, so the crumb stays light.

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