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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In an earthen bowl, combine the egg whites and lightly break them with a whip.
Whip the meringue
Sift in the cream of tartar and beat until the mixture clings to the bowl.
Gradually add the sugar while continuing to beat until stiff peaks form.
Fold and bake
Gently fold in the flour and almond extract until just combined.
Pour the batter into a prepared cake pan and bake for about 30-35 minutes, or until a toothpick comes out clean.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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.
- Fine granulated sugar
- Added gradually to stabilize the whipped foam and sweeten the cake.
- Winter wheat flour
- Provides the set structure that holds the cake once baked.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a more stable foam.
The step that matters
Folding in the flour. Overmixing knocks air out of the whipped egg whites, so the flour should be folded in gently and only until just combined to keep the cake light.
“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.
