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 Filled 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 batter
Preheat the oven to 350°F (175°C).
Cream the butter, then gradually add the sugar.
Beat in the egg yolks and milk until well combined.
Sift together the baking powder and flour, then add the sifted mixture to the batter.
Fold in the beaten egg whites until stiff.
Bake and make the filling
Bake in layers until golden.
For the lemon filling, mix the sugar, flour, egg, butter, lemon rind, and lemon juice in the order given.
Cook the filling over medium heat, stirring constantly, until it reaches boiling point.
Assemble
Assemble the cake layers with the lemon filling in between.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and add richness and tender texture to the crumb.
- Eggs
- Egg yolks bind and enrich the batter, while whipped whites add lift and structure.
- Flour
- Forms the main structure of the cake and sets as it bakes.
- Baking powder
- Releases gas in the batter to make the cake rise and become light.
- Sugar
- Sweetens the cake and helps hold air when creamed with the butter.
- Lemon juice
- Adds bright acidity that balances the sweetness of the filling.
The step that matters
Cooking the lemon filling. Stirring constantly over medium heat keeps the egg from scrambling on the bottom of the pan. Bringing it to a boil fully cooks the egg and flour, which thickens the filling.
