Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Lady Fingers

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Beat the egg yolks until thick and lemon colored.

  2. Gradually add the powdered sugar while continuing to beat.

  3. Fold in the stiffly beaten egg whites and vanilla.

  4. Gently cut and fold in the flour.

Shape and bake

  1. Shape the mixture on unbuttered parchment paper using a pastry bag and tube.

  2. Sprinkle with powdered sugar.

  3. Bake for 12 minutes in a cool oven at 300°F (150°C).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Add richness, color and fat, and help make the batter smooth.
Egg whites
Whipped into a foam, they give the batter air and lift.
Flour
Sets the structure of the batter as it bakes.
Powdered sugar
Sweetens the batter and helps it hold its beaten structure.
Vanilla
Adds aroma that comes through the baked sponge.

The step that matters

Fold in the egg whites and flour gently. Beaten egg whites hold air bubbles that give the ladyfingers their lift. Stirring or deflating the batter too hard knocks out that air, so the cookies come out flat and dense.

Swap the vanilla

How well each one fits the dish's main ingredients (egg, sugar, flour):

  1. Raisinfits better
  2. Vanillathe original
  3. Lemonfits less well
  4. Figfits less well

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