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 Food
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 the batter
Preheat the oven to 350°F (175°C).
Add the pinch of salt to the egg whites and beat until frothy.
Add the cream of tartar and continue beating until stiff peaks form.
Gradually add the sugar and flour alternately, mixing until fully combined.
Bake and cool
Pour the batter into an ungreased cake tin.
Bake for 45 minutes.
Once done, invert the cake tin over a tea cloth and let it cool completely.

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 traps air and gives the cake its light, airy structure.
- Cake flour
- Provides a light structure that sets around the air bubbles as the cake bakes.
- Granulated sugar
- Sweetens the cake and helps stabilise the whipped egg white foam.
- Cream of tartar
- Acidifies the egg whites, making the foam more stable and less likely to collapse.
The step that matters
Beating the egg whites to stiff peaks. Air whipped into the egg whites is the only leavening in an angel food cake. If the whites are under-beaten, the foam is weak and the cake rises poorly; if over-beaten, it turns dry and grainy and can collapse. Stopping at stiff, glossy peaks gives the best lift.
