Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Almond Genoa Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 300°F (150°C).
Skin and coarsely chop half of the almonds; mix with the chopped citron.
Split the remaining almonds in half for decoration.
Dredge the chopped almonds and citron with flour and warm slightly.
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the beaten egg yolks and mix well for 5 minutes.
Gently sift in the flour and fold in the beaten egg whites.
Stir in the almond and citron mixture gently.
Bake
Pour the batter into a tin lined with buttered paper.
Evenly distribute the split almonds on top.
Bake for 1 hour in a cool oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites and yolks provide structure and lift, giving the cake its airy crumb.
- Butter
- Creamed with sugar, it adds fat for a tender, rich texture.
- Sugar
- Creamed with butter, it sweetens the cake and helps create a light, fluffy batter.
- All-purpose flour
- Provides the starch that sets the crumb once the cake is baked.
- Almonds
- Add nutty flavour and a pleasant chew, and decorate the top.
- Citron
- Adds fruity, aromatic flavour and moisture throughout the cake.
The step that matters
Folding in the egg whites. Whites hold air that gives the cake its lift. Stirring them in roughly or sifting in flour too vigorously deflates the batter and produces a dense cake.
