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 ↓

Beat the egg whites until stiff.
Make the batter

Sift the baking powder with the flour.
Add the sifted mixture to the butter mixture.
Combine all ingredients.
Beat the mixture well.
Divide the batter into two jelly pans.
Bake and make the icing
Bake until golden.
Beat the egg whites for the icing until stiff.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to hold air, giving the cake its light, open structure.
- Butter
- Creamed with sugar to trap air and add richness and tender texture.
- Flour
- Provides the starch and gluten that set the cake's structure as it bakes.
- Powdered sugar
- Sweetens the cake and dissolves finely into the creamed butter for a smooth crumb.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
The step that matters
Beat the egg whites until stiff. Whites must be beaten enough to hold firm peaks so they trap air and lift the cake. Underbeaten whites collapse and give a dense cake, while overbeaten whites turn dry and grainy and lose their ability to blend smoothly into the batter.
