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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Add the egg yolks and mix well.
In a separate bowl, beat the egg whites until stiff peaks form.
Stir in the lemon zest, lemon juice, and sweet milk.
Dissolve the baking soda and add it to the mixture.
Gently fold in the beaten egg whites.
Bake
Pour the batter into a greased baking pan.
Bake at 350°F (175°C) until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and bind the batter, while whipped whites add lift and an airy crumb.
- Butter
- Creaming with sugar traps air and adds fat for a tender texture.
- Sugar
- Sweetens the cake and helps hold air when creamed with butter.
- Baking soda
- Reacts with the acidity of the lemon juice to release gas and help the cake rise.
- Lemon juice
- Adds acidity that brightens the flavour and activates the baking soda.
- Sweet milk
- Adds moisture and liquid to hydrate the flour and form the batter.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives the cake its lift. Stirring them vigorously knocks out that air, leaving a dense cake, so fold gently until no white streaks remain.
