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, Once More
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).
Do not grease the cake pan.
Beat the egg whites to stiff peaks.
Gradually sift in 1 ½ cups powdered sugar, mixing carefully.
Sift the flour and cream of tartar together four times.
Gently fold the flour mixture into the egg and sugar mixture.
Add the vanilla extract and mix lightly.
Bake and cool
Pour the batter into a tube pan without greasing or lining.
Bake for 45 minutes, keeping a pint of hot water in the oven.
Do not open the oven door for the first 20 minutes.
After baking, invert the cake to cool in the pan.
Once cool, carefully loosen the sides and remove the cake.

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 to trap air, giving the cake its light, airy structure.
- Flour
- Forms the structure that holds the cake's airy foam once baked.
- Sugar
- Sweetens the cake and stabilizes the whipped egg white foam.
- Cream of tartar
- Stabilizes the whipped egg whites, helping the foam hold its volume.
The step that matters
Do not grease the cake pan. Angel cake batter climbs the sides of an ungreased pan as it bakes, and the foam needs that grip to rise fully. Greasing causes the batter to slip and collapse as it cools.
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.
