Why it works: Butter and flour 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 ↓
Lady Fingers
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Create a funnel-shaped bag using heavy tin or strong brown paper.
Insert a funnel-shaped tin tube into the bag, securing the small end tightly around the tube.
Make and shape the batter
Beat the eggs and sugar until light and fluffy, similar to sponge cake.
Sift in the baking powder with the flour and stir slowly until combined.
Pour the batter into the bag, gathering it tightly to prevent spillage.
Quickly press the dough out through the tube onto a pan lined with light brown paper, forming pieces about the length of a finger and the thickness of a pencil.
Sprinkle the formed lady fingers with granulated sugar.
Bake and assemble
Bake in the preheated oven until golden.
Once cool, wet the underside of the paper with a brush, remove the lady fingers, and stick them together back to back.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped with sugar, they trap air that gives the sponge-like structure and lightness.
- Sugar
- Sweetens the batter, helps the eggs whip to a stable foam, and browns in the oven.
- Flour
- Provides the starch and gluten network that sets the batter into a firm, dry structure when baked.
- Baking powder
- Releases gas during baking, helping the piped pieces rise and stay light.
The step that matters
Sift the baking powder and flour in, then stir slowly. The batter's lightness comes from air whipped into the eggs and sugar. Stirring slowly and only until combined keeps that air from collapsing, so the baked pieces stay light and airy rather than dense.
