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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift the flour three times, then add the cream of tartar and sift again.
Sift the sugar three times.
Beat the egg whites to a stiff froth in a large bowl.
Make the batter
Gently add the sugar, then the flour, and finally the vanilla, while continuing to beat.
Do not stop beating until the mixture is in the pan.
Bake and cool
Bake for 40 minutes at 350°F (175°C).
If the cake is too soft when tested with a straw, leave it in the oven a few minutes longer.
Do not open the oven for the first 15 minutes.
Turn the pan upside down to cool.
Loosen the cake around the sides with a knife and remove it from the pan without greasing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into foam that traps air, giving the cake its light, airy structure.
- Powdered sugar
- Sweetens the cake and dissolves into the foam, helping it stay stable.
- Flour
- Provides the structure that sets the cake as it bakes around the trapped air.
- Cream of tartar
- Acidifies the egg whites, stabilizing the foam so it holds its volume.
The step that matters
Beating the egg whites and folding in the dry ingredients. Under-beaten whites won't hold enough air, and over-mixing or deflating the foam makes the cake dense. Keep beating until the batter goes into the pan, as the record directs.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, sugar, flour, cream):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, sugar, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
