Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Break the eggs into a bowl without beating them, then add them to the sugar.
Beat the mixture steadily for half an hour.
Stir the flour in gently.
Bake
Bake in a preheated oven at 400°F (200°C) for about 45 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Trapped air and proteins give the cake its light, risen structure and moisture.
- Sugar
- Sweetens the cake and helps hold air in the beaten egg mixture.
- Flour
- Provides the starch and gluten that set the cake's structure as it bakes.
The step that matters
Stir in the flour gently. Overmixing once flour is added develops gluten, which toughens the crumb and can knock out the air the beaten eggs trapped, leaving a dense cake.

Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
