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
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
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the sugar and butter.
Add the egg, milk, grated lemon rind, and lemon juice; mix well.
In another bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Bake
Pour the batter into greased jelly tins.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the batter and, creamed with butter, helps give a tender crumb.
- Butter
- Fat that, creamed with sugar, traps air and adds tenderness and flavor.
- Egg
- Binds the batter and adds structure as it sets in the oven.
- Flour
- Provides the structure that sets the cake's crumb as it bakes.
- Baking powder
- Releases gas that lifts the batter so the cake rises.
- Milk
- Adds moisture and helps the batter reach a smooth, pourable consistency.
The step that matters
Adding the dry ingredients. Once flour meets liquid, gluten begins to form, and stirring strengthens it. Mixing only until smooth keeps the cake tender; overmixing makes it tough and dense.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, milk, butter, flour):

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