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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Preheat the oven to 400°F (200°C).
In a bowl, mix powdered sugar and egg yolks until well combined.
Gently fold in flour and then beaten egg whites.
Pipe and bake
Transfer the batter to a piping bag and pipe strips 2 to 3 inches long onto a greased baking sheet.
Bake until lightly golden.
Finish
Once cooled, sandwich them together with frosting or icing.

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
- Egg whites
- Whipped air that gives the lady fingers their light, sponge-like lift.
- Egg yolks
- Add richness and emulsify with the sugar to give a tender crumb.
- Flour
- Provides structure so the piped strips hold their shape while baking.
- Powdered sugar
- Sweetens the batter and helps stabilise the yolks for a smooth mix.
The step that matters
Gently fold in flour and then beaten egg whites. Overmixing or deflating the beaten egg whites knocks out the air that leavens the batter, producing dense, flat cookies. Folding gently keeps the foam intact while the flour is evenly distributed.
