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 ↓

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
Sift and measure the flour and sugar. Set aside.
Make the batter
Beat the egg yolks until very stiff and frothy.
Whip the egg whites with a pinch of salt until foamy. Add the cream of tartar and continue whipping until very stiff.
Gradually add the sugar to the whipped egg whites and beat until combined.
Fold in the beaten egg yolks gently.
Fold in the flour lightly.
Bake
Pour the batter into a cake pan.
Bake in a moderate oven at 350°F (175°C) for about 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 to a stiff foam, they trap air that lifts and gives the cake its light structure.
- Egg yolks
- Beaten and folded in, they add richness and tenderness to the crumb.
- Flour
- Folded in lightly, it provides the structure that holds the airy batter as it bakes.
- Granulated sugar
- Added to the whipped whites, it sweetens the cake and helps stabilize the foam.
- Cream of tartar
- Added to the whites, it acidifies them, helping the foam whip stiffer and hold its volume.
The step that matters
Folding in the yolks and flour. Overmixing or stirring vigorously knocks air out of the whipped whites, so the cake bakes flat and dense. Fold gently with a wide motion, stopping once just combined.
