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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Mix the batter
Sift the sugar, flour, and cream of tartar together into the beaten egg whites.
Stir lightly until just combined.
Bake
Pour the mixture into an ungreased pan.
Bake at 350°F (175°C) for one hour.
Place a pan over the cake for the first half hour of baking.

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 traps air, giving the cake its light, airy structure.
- Granulated sugar
- Sweetens the cake and helps stabilize the foam while keeping the crumb tender.
- All-purpose flour
- Provides the protein and starch that set the cake's structure as it bakes.
- Cream of tartar
- Acidifies the egg whites, stabilizing the foam so it holds its volume during baking.
The step that matters
Stir lightly until just combined. Beaten egg white foam holds the cake's air. Vigorous or long stirring deflates it, so the cake bakes up dense and short instead of light.
“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.
