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.
Make the batter
Beat the egg whites to a stiff froth.
Sift the powdered sugar two or three times, then add it very lightly to the egg whites.
Sift the cream of tartar through the flour after sifting the flour alone four times.
Carefully mix the flour and cream of tartar into the egg mixture as gently as possible.
Add rose-water or lemon for flavoring.
Bake and cool
Pour the batter into a bright cake pan without buttering it.
Bake in a moderate oven at 350°F (175°C) for about 45 minutes.
Check for doneness with a straw.
Let it cool gradually by leaving the oven door open.
If the pan has a tube, turn it upside down; if not, set it upright on something.
Once completely cool, remove the cake from the pan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a stiff foam that traps air and gives the cake its structure and lift.
- Flour
- Sets the structure of the cake once heated, holding the foam in place.
- Powdered sugar
- Sweetens the cake and dissolves into the foam, adding fine texture.
- Cream of tartar
- Stabilizes the whipped egg whites, helping the foam hold its volume.
The step that matters
Folding in the flour and cream of tartar. Overmixing knocks air out of the whipped egg whites, so the cake bakes flat and dense. Mixing as gently as possible keeps the foam intact for a light sponge.
