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 very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
In a large bowl, combine the sifted sugar, flour, cream of tartar, and salt.
Make and bake the cake
Gently fold in the beaten egg whites and flavoring until just combined.
Pour the batter into a round tin with a funnel in the center; do not butter the pan.
Bake for 50 minutes, covering with paper if it begins to brown too early.
Remove from the pan and cool on a wire rack.
Frosting
For frosting, beat the egg white with baking powder and confectioners' sugar until smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Trapped air in the beaten whites gives the cake its light, airy structure.
- Cream of tartar
- Acidity helps stabilize the beaten egg white foam so it holds its volume.
- Flour
- Provides the protein and starch that set the cake's structure as it bakes.
- Granulated sugar
- Sweetens the cake and tenderizes its crumb while helping stabilize the egg foam.
The step that matters
Gently fold in the beaten egg whites. The cake's rise depends on the air held in the beaten whites. Folding gently keeps that air in the batter, while vigorous stirring deflates the foam and produces a dense, flat cake.
Swap the vanilla
How well each one fits the dish's main ingredients (sugar, flour, cream, egg):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against sugar, flour, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
