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 ↓

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.
Make the batter
Preheat oven to 350°F (175°C).
Cream sugar and butter until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Stir in milk.
In a separate bowl, combine flour and baking powder, then gradually add to wet mixture.
Make the filling
For the filling, combine grated apples, lemon rind, ½ cup sugar, 1 egg, and a small piece of butter in a saucepan.
Cook filling until warm, then set aside.
Assemble and bake
Pour half of cake batter into greased pan.
Spread warm filling over batter, then top with remaining batter.
Bake 25-30 minutes or until a toothpick inserted in the center comes out clean.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cake a tender crumb and richness.
- Eggs
- Bind the batter and add structure, richness and moisture as the cake sets.
- Flour
- Forms the cake's main structure once it sets in the oven.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Grated apples
- Add moisture and fruity flavour to the filling and the cake.
- Sugar
- Sweetens the cake and helps it brown and keep its tender texture.
The step that matters
Adding the warm filling between batter layers. If the filling is hot or the batter is too thin, the layers can mix or sink. Spreading the filling warm but not hot over half the batter keeps the layers distinct while the cake sets.
Swap the apple
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, flour, lemon):

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