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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Sift the flour with the cream of tartar five times.
Sift the powdered sugar.
Make the batter
Beat the egg whites to a stiff froth.
Gradually stir the sugar into the egg whites very lightly.
Add the vanilla extract and mix gently.
Quickly fold in the flour until just combined.
Pour the batter into a clean, ungreased cake pan.
Bake and cool
Bake in a preheated oven at 350°F (175°C) for about 40 minutes.
Test for doneness with a broom splint.
Once done, invert the cake pan onto two saucers 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 stiff foam that gives the cake its light, airy structure.
- Flour
- Provides the structure that holds the airy foam once set in the oven.
- Powdered sugar
- Sweetens the cake and dissolves into the whipped whites, adding stability to the foam.
- Cream of tartar
- Stabilizes the whipped egg whites, helping the foam hold its volume.
- Vanilla extract
- Adds aroma and flavor to the batter.
The step that matters
Fold in the flour quickly and gently. Egg white foam loses air when overmixed or left standing, so the flour should be folded in just until combined and the batter baked promptly to keep the cake light.
Swap the vanilla
How well each one fits the dish's main ingredients (flour, cream, sugar, egg):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against flour, cream, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
