Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. 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).
Make the batter
Whip the egg whites with a pinch of salt until half whipped.
Add the cream of tartar and continue whipping until very stiff.
Gradually add the sugar while beating until well combined.
Flavor the mixture as desired.
Gently fold in the sifted flour.
Sift the flour 4 times and the sugar 2 times before adding.
Bake
Pour the batter into an ungreased tube pan.
Bake for 30 to 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 into foam that gives the cake its light, airy structure.
- Sugar
- Sweetens the cake and helps stabilize the whipped egg white foam.
- Flour
- Provides light structure once folded in and set by baking.
- Cream of tartar
- Stabilizes the egg white foam so it whips stiffer and holds its volume.
The step that matters
Fold in the flour gently. Overmixing knocks air out of the whipped egg white foam, so the cake rises less and turns dense. Folding keeps the foam intact.
“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.
