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 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.
Make the cake
Preheat the oven to 350°F (175°C).
Cream butter and sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Stir in flour and milk until just combined.
Pour batter into greased cake pan and bake for 25-30 minutes.
Make the lemon jelly
For the jelly, combine 1 cup sugar, 2 eggs, lemon juice, and lemon rind in a saucepan.
Add 1 teacup of water and boil until it reaches a jelly-like consistency.

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, giving the cake a light, tender crumb.
- Eggs
- Provide structure and richness, setting the cake as they cook and binding the batter.
- Flour
- Forms the cake's structure once heated, holding its shape as it bakes.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed with butter.
- Lemon juice
- Adds acidity and bright lemon flavour to the jelly.
The step that matters
Stir in flour and milk until just combined. Overmixing once flour is added develops gluten, which can make the cake tough and dense. Mix only until no dry flour remains.

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