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 ↓
Citron 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 the batter
Preheat your oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the milk and mix well.
In a separate bowl, combine the flour, corn starch, and baking powder.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Fold in the candied citron.
Add the egg whites and bake
In another bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the batter.
Pour the batter into a greased cake pan and bake for about 30-40 minutes, or until a toothpick comes out clean.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air and adds richness and tender texture.
- Sugar
- Creamed with butter to add sweetness and help create a light, fluffy base.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Egg whites
- Whipped to stiff peaks, they add lift and a light, airy crumb.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Candied citron
- Adds bursts of sweet, citrus-like flavor and chew throughout the cake.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives the cake its lift. Stirring them in vigorously knocks out air, so fold gently until just combined to keep the cake light.
