Why it works: Lemon and cinnamon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 7,950 recipes. Both carry beta-phellandrene, which smells minty, terpene. 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.
Make the batter
Beat together 1 lb. sifted sugar and 4 eggs for 1 hour.
Add 1 lb. dried and sifted flour, the juice of 1 lemon, and the grated rind of 1 lemon.
Bake
Bake in a slow oven at 300°F (150°C).
Alternative method
Alternatively, boil 1 lb. loaf sugar in 1 pint of water.
Whisk it with 8 eggs until cold, then stir in 1 lb. fine flour.
Keep beating until ready to put into the oven, which should be hot at 400°F (200°C) for about 1 hour.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Whisked eggs trap air that lifts and sets the crumb.
- Flour
- Starch and proteins set during baking to form the loaf's structure.
- Sugar
- Sweetens the bread and helps stabilise the beaten egg foam.
- Lemon juice
- Adds acidity and brightness that balance the sweetness.
The step that matters
Keep beating until the oven is ready. Beaten eggs hold air bubbles that give the loaf its rise. If the foam collapses while waiting, the bread will be denser, so keep beating until it goes in the oven.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, flour, cinnamon):

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