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.
Make the cake
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter until light and fluffy.
Add the milk and eggs, mixing well.
Sift the baking powder with the flour and gradually add to the mixture.
Pour the batter into jelly tins and bake until golden.
Make the filling
For the filling, combine 1 cup sugar, lemon juice, lemon rind, and hot water in a double boiler.
Add the heaping teaspoon of butter and the dissolved cornstarch or flour.
Stir until the mixture thickens, then add the yolks of 2 eggs.
Assemble
Spread the filling between the layers of cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and enrich the filling, adding structure and richness when set.
- Butter
- Adds tenderness and richness to the cake crumb and gives the filling body.
- Flour
- Provides the structure of the cake and thickens the filling with cornstarch or flour.
- Sugar
- Sweetens the cake and filling and helps browning in the baked layers.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Milk
- Adds moisture to the batter and helps form a tender crumb.
The step that matters
Stir the filling until it thickens. Starch must be heated while stirring so its granules swell and gelatinize; stopping too early leaves a runny filling, and adding the egg yolks too hot can scramble them.
Swap the lemon

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