Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. 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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Beat the egg whites to a stiff froth.
Gradually beat in the sugar.
Measure the flour again after the last sifting and mix in the cream of tartar.
Sift the flour mixture into the egg whites, stirring gently.
Add the vanilla extract and mix gently.
Bake and cool
Bake immediately in an ungreased pan lined with wet paper.
Bake for 40 minutes in a moderate oven at 350°F (175°C).
When done, turn the pan upside down on a sifter and leave until completely cool.
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 traps air, giving the cake its light, airy structure.
- All-purpose flour
- Provides the light starch framework that sets the cake's crumb once baked.
- Fine granulated sugar
- Stabilises the whipped egg white foam and adds sweetness to the crumb.
- Cream of tartar
- Acidifies the egg whites, helping the foam stay stable and hold its volume.
The step that matters
Sift the flour mixture into the egg whites, stirring gently. Egg white foam holds its air only while it stays intact. Vigorous stirring deflates it, leaving a dense cake instead of a light, airy one.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, flour, sugar, cream):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, flour, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
“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.
