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 ↓
White Sponge Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a mixing bowl, beat the egg whites until stiff.
Gradually add the sugar while continuing to beat until well combined.
Gently fold in the flour and cream of tartar.
Add flavoring to taste.
Pour the batter into flat tins.
Bake and serve
Bake until golden brown.
If desired, ice with chocolate icing and cut into diamond shapes.

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.
- White sugar
- Sweetens the cake and helps stabilize the whipped egg white foam.
- Flour
- Provides the set structure that holds the cake's airy crumb together as it bakes.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a stronger, more stable foam.
The step that matters
Beat the egg whites until stiff. Under-whipped whites will not hold enough air, so the cake will be dense. Over-whipped whites turn dry and grainy and collapse, so fold gently after beating.
“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.
