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 ↓
Sunshine 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
Beat the egg whites until stiff peaks form.
Add the cream of tartar and gradually mix in the sugar, sifting it three times.
Gently fold in the beaten egg yolks.
Carefully stir in the flour.
Bake and cool
Pour the batter into a cake pan and bake for 50 minutes.
Once baked, invert the cake in the pan to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they trap air and give the cake its light, airy structure.
- Egg yolks
- Folded in gently, they add richness and moisture while keeping the foam intact.
- Granulated sugar
- Sweetens the cake and helps stabilize the whipped egg white foam.
- Flour
- Provides the starch and gluten network that sets the cake's crumb once baked.
- Cream of tartar
- Acidifies the egg whites, stabilizing the foam so it holds its peaks.
The step that matters
Gently fold in the beaten egg yolks. Whipped egg white foam holds the cake's rise. Heavy or vigorous mixing deflates it, so the yolks and flour should be folded in gently to keep the air trapped in the batter.
“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.
