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 ↓
Lady Fingers
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
Mix sugar with egg yolks in a bowl.
Add flour and lemon extract, and mix well.
Beat egg whites until stiff and gently fold into the mixture.
Shape and bake
Squeeze the batter through a funnel made of writing paper onto greased parchment in a dripping pan.
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
- Egg whites
- Beaten until stiff, they trap air that lifts the batter and gives the cookies a light, airy crumb.
- Egg yolks
- Add richness and moisture, and help bind the batter with the sugar.
- Flour
- Provides structure that holds the piped shape as the batter sets in the oven.
- Sugar
- Sweetens the batter and helps the yolks whip into a smooth, stable base.
The step that matters
Fold the beaten egg whites gently. Stiff whites hold the air that makes the ladyfingers light. Stirring or deflating them vigorously knocks out that air, so the batter bakes up flat and dense instead of tender and spongy.

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