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
Preheat the oven to 350°F (175°C).
Line an ungreased cake pan with parchment paper.
Make the batter
Sift together the flour, cream of tartar, and sugar ten times.
In a large mixing bowl, beat the egg whites to stiff peaks using a wire whisk.
Gently fold in the vanilla and the sifted flour mixture until just combined.
Bake
Pour the batter into the prepared pan and bake for 40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they trap air and give the cake its light, airy structure.
- Cream of tartar
- Stabilizes the whipped egg whites, helping them hold their peaks longer.
- Granulated sugar
- Sweetens the cake and helps stabilize the whipped egg white foam.
- All-purpose flour
- Provides the light structure that sets the cake's crumb once baked.
The step that matters
Folding in the flour mixture. Overmixing knocks air out of the whipped egg whites, which makes the cake dense. Fold gently, only until combined, so the foam keeps its volume.
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.
