Why it works: Flour and butter 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 ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Cream the butter and sugar together until light.
Sift the flour.
Weigh and sift again with baking powder.
Mix and bake
Gradually mix in the flour and beaten egg whites until stiff and frothy.
Add the flavoring and mix until smooth.
Bake in a slow oven (300°F / 150°C), covering with paper until risen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake's crumb once baked.
- Sugar
- Adds sweetness and, creamed with butter, helps give a fine, tender texture.
- Butter
- Adds fat for a tender, rich crumb and carries flavor.
- Egg whites
- Trap air when beaten, giving the batter lightness and structure as it sets.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
The step that matters
Folding in the beaten egg whites. The air trapped in beaten whites gives the cake its lift. Mixing gently and only until combined keeps that foam from collapsing, while overmixing deflates it and makes a denser cake.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
