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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the cake
Cream the butter and sugar together.
Add the milk, half of the flour, and the beaten yolks of the eggs. Beat for 10 minutes.
Fold in the beaten egg whites and the remaining flour with the baking powder sifted in.
Bake in a quick oven at 400°F (200°C) until soft.
Make the filling and assemble
For the filling, mix hot water, sugar, and flour.
Add one beaten egg, lemon juice, and grated lemon rind. Boil until thickened. Let it cool.
Spread between the cake layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and structure, while whipped whites trap air that lifts the cake.
- Butter
- Fat that tenderises the crumb and carries flavour.
- Flour
- Starch and gluten set during baking to give the cake its structure.
- Baking powder
- Releases gas when heated, helping the cake rise and become light.
- Sugar
- Sweetens the cake and helps keep it moist and tender.
- Lemon juice
- Adds acidity and bright lemon flavour to the filling.
The step that matters
Folding in the beaten egg whites. Whites hold the air that makes the cake rise. Folding gently keeps that air in; stirring hard deflates the batter and yields a flatter, denser cake.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, butter, flour, milk, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against sugar, butter, flour, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
