Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
To Make Lemon-Cakes a Second Way
Ingredients
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 the egg whites with a whisk for 1 hour with the flower water.
Mix in the sugar and grated lemon rind until well combined.
Add the lemon juice and smooth egg yolks, mixing thoroughly.
Stir in the flour just before transferring to the oven.
Bake
Grease the pan and bake in a moderate oven at 350°F (175°C) for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whisked to foam, they trap air and give the cake its light, risen structure.
- Egg yolks
- Add richness and tenderness and help bind the batter as it sets.
- Sugar
- Sweetens the cake and helps stabilise the whisked egg foam.
- Flour
- Forms the set structure of the crumb as the batter bakes.
- Lemon juice
- Adds acidity and bright flavour that balances the sweetness.
The step that matters
Stir in the flour just before transferring to the oven. Flour begins to build gluten once wet and mixed, and the air in the whisked egg whites slowly collapses. Adding flour late and moving the batter to the oven promptly keeps the cake light and prevents it from becoming dense or deflating.
Swap the lemon
How well each one fits the dish's main ingredients (egg, rose, sugar, flour, butter):

- Figfits about as well
Fit is the average pairing score against egg, rose, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
