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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 400°F (200°C).
Cream the butter and sugar together until light and fluffy.
Add the egg yolks, milk, lemon juice, and lemon rind, mixing well.
In a separate bowl, beat the egg whites until stiff peaks form.
Fold the egg whites into the batter gently.
Sift the baking soda with the flour and gradually add it to the mixture until you achieve a tolerably thin batter.
Bake
Pour the batter into a greased cake pan and bake for about 25-30 minutes or until a toothpick 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
- Eggs
- Yolks enrich and bind the batter, while whipped whites add air and lift for a light crumb.
- Butter
- Creamed with sugar, it traps air and adds richness and tenderness to the cake.
- Sugar
- Creams with butter to aerate the batter and adds sweetness and gentle browning.
- Flour
- Provides the structure that sets the cake as it bakes.
- Baking soda
- Reacts with the acidity of the lemon to release gas that helps the cake rise.
The step that matters
Folding in the egg whites. Whipped whites hold the air that lifts the cake. Stirring them in vigorously knocks that air out, leaving a dense, flat crumb. Fold gently, just until no white streaks remain.

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