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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat together the eggs and sugar until well combined.
Add the flour, lemon juice, and grated lemon peel; mix until smooth.
Pour the batter into a baking dish.
Bake
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked with sugar, they trap air and provide structure as the cake sets.
- White sugar
- Beaten with the eggs for volume and sweetness, and helps the crumb brown.
- Flour
- Provides the structure that holds the cake together once the proteins set in the oven.
- Lemon juice
- Adds acidity that brightens the flavour of the cake.
- Grated lemon peel
- Contributes aromatic lemon oils that give the cake its fragrance.
The step that matters
Beat the eggs and sugar until well combined. The whisked eggs and sugar hold the air that lifts this cake. Under-beating leaves a dense crumb, while the flour must be folded in gently so the trapped air is not lost.

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