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 ↓
Aunt Phebe's 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the cake
Preheat your oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the milk and lemon juice and zest.
Combine the flour and baking powder in a separate bowl.
Gradually add the dry mixture to the wet mixture.
Pour the batter into prepared cake pans.
Bake for 25-30 minutes or until a toothpick comes out clean.
Make the filling
For the filling, beat the egg yolks and whites separately until fluffy.
Combine the egg yolks, sugar, and butter in a saucepan over low heat, stirring until thickened.
Remove from heat.
Stir in the lemon juice and zest.
Assemble
Once the filling is cool, spread it between the layers of the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure of the cake crumb.
- Unsalted butter
- Adds fat and tenderness, and carries flavour through the batter.
- Granulated sugar
- Sweetens the cake and helps create a light, fluffy creamed texture.
- Eggs
- Add structure, richness and moisture, and help bind the batter.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Lemon
- Adds acidity and bright citrus aroma to both the cake and filling.
The step that matters
Thicken the filling over low heat. Egg yolks can scramble if the mixture gets too hot. Cooking gently and stirring constantly lets the yolks thicken the custard smoothly without curdling.
Swap the lemon
