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 slow oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift the flour and cream of tartar together 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 then the flour, stirring quickly and lightly.
Bake and cool
Pour the mixture into a clean, ungreased cake pan.
Bake at 400°F (200°C) for about 40 minutes.
Once done, invert the cake pan onto two saucers to cool, allowing air to circulate.

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 set structure once its starch cooks in the baked batter.
- Powdered sugar
- Sweetens the batter and dissolves into the whipped whites, helping keep the foam stable.
- Cream of tartar
- Stabilizes the whipped egg whites so the foam holds its volume longer.
- Vanilla extract
- Adds aroma and flavor to the cake.
The step that matters
Stirring the flour in lightly. Egg white foam holds the cake's air, and vigorous stirring at this stage deflates it. Folding quickly and gently keeps the batter light so the cake rises well in the oven.
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.
