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 ↓

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
Add a pinch of salt to the egg whites and beat until frothy.
Add the cream of tartar and continue beating until stiff peaks form.
Gradually beat in the sugar until well combined.
Fold in the almond flavoring and sifted flour gently.
Pour the batter into an ungreased tube pan.
Bake
Bake in a preheated oven at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a foam that gives the cake its light, airy structure.
- Sugar
- Stabilizes the whipped whites and adds sweetness and a tender texture.
- Sifted all-purpose flour
- Provides light structure so the cake sets around the air bubbles.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a stable, stiff foam.
The step that matters
Folding in the flour and almond flavoring. Folding gently keeps the air trapped in the whipped egg whites. Stirring or deflating the batter makes the cake dense and reduces its rise.
