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
Preheat the oven to 350°F (175°C).
Sift the cream of tartar with the flour.
Make the batter
Beat the egg whites to stiff peaks.
Gradually add the sugar to the egg whites while beating.
Add the vanilla and sifted flour, stirring quickly and lightly.
Bake
Pour the batter into an ungreased pan.
Bake for 40 minutes without greasing the pan.

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 foam that gives the cake its airy structure and lift.
- Cream of tartar
- Acidifies the egg whites, helping the foam stay stable while it is beaten.
- Granulated sugar
- Sweetens the cake and, added gradually, helps stabilise the beaten egg white foam.
- Pastry flour
- Provides the structure that sets as the cake bakes and holds the foam's air in place.
The step that matters
Stir the flour in quickly and lightly. Egg white foam holds air only while it is intact. Overmixing when adding the flour knocks air out of the foam, leaving a dense, flat cake.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, sugar, flour, cream):
- Raisinfits about as well
- Vanillathe original
- Figfits less well
- Strawberryfits less well
Fit is the average pairing score against egg, sugar, flour, cream. 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.
