Why it works: Flour and sugar 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

Oven, in the book's wordsA quick oven

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.

Make the batter

  1. Preheat the oven to 400°F (200°C).

  2. Whip the egg whites until frothy, then gradually add half the sugar while continuing to beat until stiff.

  3. Add the egg yolks and the remaining sugar, mixing well.

  4. Gently fold in the flour until evenly combined.

Pipe and bake

  1. Using a piping bag with a small tube, pipe the mixture onto parchment paper, spacing them an inch apart.

  2. Sift a little powdered sugar over the piped mixture and shake off the excess.

  3. Place the parchment paper on a baking pan and bake until lightly golden.

Finish

  1. Once cooled, dampen the back of the parchment with a brush or sponge to easily remove the lady fingers.

  2. Pair them up by sticking two of uniform size together.

Flour and egg 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

Eggs
Whipped whites give the batter its airy structure, and the yolks add richness and color.
Sugar
Sweetens the batter and helps stabilize the whipped egg whites.
Flour
Provides the light structure that holds the piped shape once baked.

The step that matters

Folding in the flour. Folding gently keeps the air whipped into the egg whites. Stirring hard deflates the batter, so the ladyfingers bake up flat and dense instead of light and spongy.
