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 slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat your oven to 300°F (150°C).
Make the batter
In a bowl, beat together the sugar and eggs for 1 hour.
Add the flour, lemon juice, and grated lemon rind, mixing until well combined.
Bake
Pour the mixture into a baking dish and bake in the preheated oven until set.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure as they set, holding the batter together and giving it lift.
- Flour
- Forms the main structure of the bread once heated and set.
- Sugar
- Sweetens the bread and, when beaten with eggs, helps trap air for a lighter texture.
- Lemon juice
- Adds acidity and bright flavour that balances the sweetness.
The step that matters
Beating the sugar and eggs. Beating eggs with sugar for a long time incorporates air and dissolves sugar, which gives the batter volume and a lighter crumb. Under-beating leaves a dense bread, and the record's one-hour beating time should be followed as written.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, flour):

- 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.
