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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream together the sugar and butter.
Add the yolks of the eggs and mix well.
Stir in the milk and the beaten egg whites.
Sift in some of the flour and mix thoroughly.
Add the lemon juice and grated rind, then finish with the remaining flour.
Bake
Pour the batter into shallow pans and bake for 30 to 45 minutes.

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 and beaten whites add richness and help the cake rise and hold its structure.
- Flour
- Provides the structure that sets as the cake bakes.
- Butter
- Creamed with sugar, it traps air and adds tenderness and fat for a moist crumb.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Milk
- Adds moisture and liquid so the flour can hydrate and form the batter.
- Lemon
- Juice adds acidity and bright flavour, while the grated rind adds aroma.
The step that matters
Creaming the sugar and butter. Beating them together traps air in the fat, which helps lighten the batter and gives the cake a tender crumb. Under-creaming leaves a dense texture.
