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 ↓

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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Beat the egg whites with the cream of tartar until stiff peaks form.
Sift the powdered sugar into the egg whites and gently fold it in with an egg beater.
Sift the flour five times, then slowly sift it into the egg and sugar mixture.
Add the vanilla extract and fold gently.
Bake and cool
Grease a cake pan lightly with butter and line the bottom with greased unglazed paper.
Pour the batter into the pan and bake for 40 minutes, placing a pan of water in the oven.
Remove from the oven, invert the pan, and let it cool until the cake falls out.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into stiff peaks to form the airy foam that gives the cake its structure and lift.
- Cream of tartar
- Stabilizes the whipped egg whites, helping the foam hold its shape longer.
- Powdered sugar
- Sweetens the cake and dissolves into the foam, adding fine texture.
- All-purpose flour
- Provides the light starch framework that sets the cake's crumb once baked.
The step that matters
Folding the flour and sugar into the egg whites. Folding gently keeps the air bubbles in the whipped whites intact. Stirring or deflating the foam makes the cake dense and short instead of light and tall.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, cream, sugar, flour):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, cream, sugar, flour. 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.
