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
Preheat the oven to 350°F (175°C).
Sift the flour and measure it after sifting.
Sift the sugar and set it aside.
Make the batter
Beat the egg whites to a stiff froth.
Gradually add the sugar while continuing to beat.
Gently fold in the flour and flavoring.
Pour the batter into an ungreased pan.
Bake and cool
Bake for 1 hour.
Turn the pan upside down to cool.

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 and gives the cake its light, airy structure.
- Cream of tartar
- Acidifies the whites, helping the foam stay stable and resist collapsing.
- Sugar
- Dissolves into the whipped whites, strengthening the foam and adding sweetness.
- All-purpose flour
- Provides gentle structure once baked, supporting the airy foam as it sets.
The step that matters
Gently fold in the flour and flavoring. Egg white foam holds air only while intact. Vigorous stirring deflates it, so the cake bakes dense instead of light and tall.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, cream, flour, egg):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against sugar, cream, flour, egg. 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.
