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 slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the eggs with the sugar for 1 hour.
Add the flour, lemon juice, and grated lemon rind.
Mix until well combined.
Bake
Bake in a slow oven at 300°F (150°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten with sugar to trap air, giving the bread lift and a light, airy structure.
- Sugar
- Sweetens the bread and, when beaten with eggs, helps hold air bubbles in the batter.
- Flour
- Provides the structure that sets as the bread bakes and firms up.
- Lemon juice
- Adds acidity and bright flavour that balances the sweetness of the sugar.
The step that matters
Beat the eggs with the sugar. Beating eggs and sugar together traps air in the mixture, which gives the bread its lift. Under-beating leaves it dense, so the batter needs sustained beating rather than a quick stir.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, flour):
- Raisinfits better
- Vanillafits better
- Lemonthe original
- Figfits about as well
Fit is the average pairing score against sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
