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 ↓
Angel Cake
Ingredients
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.
Prepare
Preheat your oven to 350°F (175°C).
Add a pinch of salt to the egg whites and whip them to a foam.
Add the cream of tartar and continue whipping until very stiff.
Make the batter
Gently fold in the sifted sugar and then the bitter almond extract.
Gradually fold in the flour very lightly; do not beat.
Pour the batter into an ungreased Van Dusen pan.
Bake and cool
Bake for 1 hour, until the cake rises and is lightly browned.
When the top is browned, place a pan of cold water above the cake to prevent scorching.
Remove the cake from the oven and invert it to cool in the mold.

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 traps air, giving the cake its light, airy structure.
- Granulated sugar
- Sweetens the cake and, folded into stiff whites, helps stabilize the foam.
- All-purpose flour
- Provides the light structure that sets the cake as it bakes.
- Cream of tartar
- Stabilizes the whipped egg whites so the foam holds its volume longer.
The step that matters
Folding in the flour. Overmixing or beating after the flour goes in deflates the air bubbles in the whipped whites, which makes the cake dense instead of light. Fold gently and only until the flour disappears.
“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.
