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 slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Sift the flour four or five times.
Measure and set aside 1 cup of sifted flour.
Sift the granulated sugar.
Measure 1¼ cups of sifted sugar.
Make the batter
Beat the egg whites until frothy.
Add the cream of tartar to the egg whites.
Beat the mixture until very stiff.
Gently stir in the sugar.
Gently stir in the flour, being careful not to deflate the egg whites.
Pour the batter into an ungreased pan that has been wet with cold water.
Bake
Bake for 50 minutes.

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.
- Granulated sugar
- Sweetens the cake and helps stabilise the whipped egg white foam.
- Flour
- Provides the light structure that sets around the air bubbles as the cake bakes.
- Cream of tartar
- Acidifies the egg whites, helping them whip to a stronger, more stable foam.
The step that matters
Gently stir in the flour. Folding rather than stirring keeps the air bubbles in the whipped egg whites intact. Deflated foam produces a dense cake with less rise.
