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 ↓
Angel Cake
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 the batter
Sift together the flour and cream of tartar five times.
Beat the egg whites until stiff.
Carefully fold in the powdered sugar and vanilla extract.
Add the flour, stirring quickly and lightly.
Bake and cool
Bake in an unbuttered angel cake tin at 350°F (175°C) for about 40 minutes.
When done, invert the cake in the tin, resting the edges on two saucers for easy removal.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
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, they trap air and give the cake its light, airy structure.
- Flour
- Provides the set structure that holds the whipped foam once baked.
- Powdered sugar
- Sweetens the cake and dissolves into the foam, helping it stay stable and tender.
- Cream of tartar
- Stabilizes the whipped egg whites so the foam holds its volume longer.
The step that matters
Folding in the flour. Stirring too vigorously deflates the whipped egg white foam, which removes the air that makes the cake rise and turns it dense. Stir quickly and lightly, just until combined.
Swap the vanilla
How well each one fits the dish's main ingredients (flour, cream, egg, sugar):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against flour, cream, egg, sugar. 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.
