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 ↓
Angels' Food
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift together the powdered sugar, flour, and cream of tartar four times.
In a separate bowl, beat the egg whites to stiff peaks.
Make and bake the batter
Gently fold in the sifted flour and sugar mixture along with the vanilla or lemon extract and a pinch of salt.
Pour the batter into an ungreased angel food cake pan.
Bake at 300°F (150°C) for 40 to 50 minutes without opening the oven for the first 15 minutes.
Cool
Once baked, invert the pan on its feet until the cake is 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 stiff peaks, they trap air and form the cake's light, airy structure.
- Powdered sugar
- Sweetens the cake and, being fine, blends smoothly into the whipped whites.
- Flour
- Provides the light structure that holds the cake's airy crumb as it bakes.
- Cream of tartar
- Stabilizes the whipped egg whites, helping them hold their peaks.
The step that matters
Folding in the flour and sugar mixture. Folding gently preserves the air whipped into the egg whites. Stirring or deflating the batter makes the baked cake dense and reduces its rise.
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.
