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 ↓
Delicate Cake
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Grease a pan and line the bottom with greased light brown paper.
Make the batter
Cream the butter until light.
Add the powdered sugar and beat well.
Beat the egg whites until stiff.
Add the egg whites alternately with the flour to the butter mixture.
Flavor with 2-3 drops of bitter almond extract.
Let the batter rise for 1 hour.
Bake
Bake for 30 minutes.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they add lift and an airy crumb to the batter.
- Butter
- Creamed with sugar, it adds richness and a tender texture.
- Flour
- Provides the starch and structure that hold the cake together as it bakes.
- Powdered sugar
- Sweetens the batter and dissolves smoothly into the creamed butter.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
The step that matters
Beat the egg whites until stiff. Stiff egg whites trap air that expands in the oven and gives the cake its lift. Under-whipped whites collapse, and over-whipped whites turn dry and grainy, so both can leave a dense result.
“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.
