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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Beat the eggs with the sugar and butter until well combined.
Add the milk and mix well.
Dissolve the baking soda in the milk and add it to the mixture.
Sift the flour with the cream of tartar and gradually stir it into the batter.
Add the grated lemon rind and the juice of the lemon.
Bake
Pour the batter into a greased cake pan and bake immediately.

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
- Eggs
- Provide structure and richness, and help bind the batter.
- Sugar
- Adds sweetness and helps give the cake a tender crumb.
- Butter
- Adds fat for a tender texture and rich flavour.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking soda
- Reacts with the acidic ingredients to release gas that helps the cake rise.
- Cream of tartar
- Adds acidity that reacts with the baking soda, supporting the rise.
The step that matters
Bake immediately after mixing in the leavening. Baking soda and the acid in the batter start releasing gas as soon as they are combined. If the batter waits, much of that gas escapes before the heat sets the structure, which can leave the cake flatter and denser.
