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.
In a separate bowl, combine the baking powder and flour, then gradually add to the wet mixture.
Divide the batter into 5 layers and bake until golden.
Make the jelly and assemble
For the jelly, combine the grated lemon rind, lemon juice, 1 cup sugar, 1 egg, and ½ cup water in a saucepan.
Add 1 teaspoon butter and 1 tablespoon flour mixed with a little water.
Boil until thickened, then let cool.
Spread the jelly 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, in the jelly, thicken it and add richness.
- Flour
- Provides the structure that holds the cake's crumb together.
- Butter
- Adds fat and tenderness and carries flavour in the cake.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Lemon juice
- Adds acidity and bright flavour to the jelly filling.
The step that matters
Boil the jelly until thickened. The jelly thickens as the flour starch and egg cook in the hot liquid. Undercooked, it stays runny and soaks into the layers; overcooked, it can turn stiff or scorch on the bottom of the pan.
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.
