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 ↓

Ingredients
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
Beat the sugar and eggs together for one hour.
Add the flour, lemon juice, and grated lemon rind. Mix until well combined.
Pour the batter into a prepared baking pan.
Bake
Bake in a 400°F (200°C) oven for about one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten with the sugar to trap air, giving the cake lift and a light, airy crumb.
- Sugar
- Sweetens the cake and, beaten with the eggs, helps build a fine, tender structure.
- Flour
- Provides the structure that sets as the cake bakes, holding its shape.
- Lemon rind
- Adds the aromatic oils that give the cake its lemon flavour.
- Lemon juice
- Adds acidity and bright lemon flavour that balances the sweetness.
The step that matters
Beating the sugar and eggs for one hour. Beating eggs and sugar incorporates air that gives the cake its rise. Under-beating leaves a dense crumb, while the long beating time must be sustained so the foam stays stable before the flour is folded in gently.

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