Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Citron Pound 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).
Line two cake tins with buttered paper.
Make the batter
In a large bowl, beat the butter to a cream.
Gradually beat in the powdered sugar, then the flour and salt.
Add the eggs one at a time, mixing well after each addition.
Stir in the brandy and the chopped citron.
Bake
Pour the batter into the prepared cake tins and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Add structure and richness, and help bind the batter as it bakes.
- All-purpose flour
- Provides the main structure that holds the cake together as it sets.
- Powdered sugar
- Sweetens the cake and, creamed with butter, helps create a fine, even texture.
- Brandy
- Adds aroma and flavor, and a little moisture to the batter.
- Candied citron
- Adds bright, sweet-tart citrus flavor and chewy bits throughout the cake.
The step that matters
Beating the butter to a cream. Beating softened butter with sugar traps air in the fat, which helps the cake rise and gives it a light, even crumb. Butter that is too cold or too warm will not cream properly.
