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 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 in a large bowl.
Beat in the powdered sugar, flour, and salt.
Add the eggs, yolks and whites beaten separately.
Stir in the brandy.
Fold in the floured citron slices.
Bake
Line two cake pans with buttered paper and pour in the batter.
Bake at 350°F (175°C) for about 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and give the cake a rich, tender crumb.
- Eggs
- Add structure as they set, and their yolks and whites add richness and lift.
- Flour
- Forms the main structure of the cake as the batter sets in the oven.
- Powdered sugar
- Sweetens the cake and helps the butter cream to a light, fine texture.
- Citron
- Adds bright, candied fruit flavour and chewy pieces throughout the cake.
- Brandy
- Adds aroma and flavour to the cake.
The step that matters
Fold in the floured citron slices.. Folding gently keeps the air beaten into the batter. Flouring the citron helps keep the slices spread evenly instead of sinking to the bottom of the pans.
