Why it works: Milk and butter 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
Prepare the cake batter
Separate the whites from the yolks of three eggs.
Beat the whites very stiff.
Add one whole egg and one scant cup butter, and cream well into two cups sugar, one cup milk, three and one-fourth cups flour, and two teaspoons Royal Baking Powder sifted into the flour.
Flavor with vanilla.
Mix and bake in three layers.
Make the lemon filling
Grate the rind of one lemon and squeeze the juice.
Combine grated rind, juice, one cup sugar, and butter the size of an egg.
Cook the mixture in a double boiler until it resembles custard.
Let cool and spread on the cake layers as deep as desired, or use all.
If the lemon is small, use two rinds instead of one.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites beaten stiff add lift and an airy structure to the batter.
- Flour
- Forms the cake's structure once mixed with the liquids and eggs.
- Butter
- Creamed with the sugar to add tenderness and richness to the crumb.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Royal baking powder
- Releases gas in the batter so the cake rises in the layers.
- Lemon
- Adds acidity and bright aroma to the cooked custard filling.
The step that matters
Cooking the lemon custard in a double boiler. Gentle indirect heat lets the eggs and sugar thicken smoothly; direct high heat can curdle or scorch the mixture.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, milk, flour, egg, butter):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against sugar, milk, flour, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
