Why it works: Cream and sugar 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 cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the egg whites until foamy, then add cream of tartar and beat until stiff peaks form.
Gradually add granulated sugar, beating well after each addition.
Add powdered sugar in the same manner.
Stir in the egg yolks until well mixed.
Add flour and beat for 15 seconds.
Bake
Pour batter into cake tins, filling them only half full.
Bake in a cool oven at 300°F (150°C) until done.

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.
- Cream of tartar
- Stabilizes the whipped egg whites so the foam holds its shape longer.
- Granulated sugar
- Added gradually to the whites, it helps stabilize the foam and adds sweetness.
- Powdered sugar
- Adds sweetness and a fine texture to the batter.
- Egg yolks
- Add richness, moisture and fat, and help bind the batter.
- Flour
- Provides the starch and gluten network that gives the cake its set structure.
The step that matters
Folding in the flour. Beating the flour in too vigorously can knock air out of the whipped whites and develop gluten, leaving a dense cake. Keep the mixing brief, as the record specifies 15 seconds.
