Lady Fingers

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Mix the sugar and egg yolks well.

  2. Add the flour and a pinch of salt.

  3. Beat the egg whites to stiff peaks.

  4. Gently fold the egg whites into the mixture a little at a time.

Shape and bake

  1. Butter a shallow pan.

  2. Use a piping bag or rolled paper to squirt the mixture onto the pan.

  3. Dust with sugar and bake at 350°F (175°C) until lightly golden.

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 whites
Whipped to stiff peaks, they trap air that lightens the batter and helps it rise.
Egg yolks
Add richness and emulsify with the sugar, giving the batter body and tenderness.
Flour
Provides structure that sets the piped shapes as they bake.
Sugar
Sweetens the batter and helps stabilise the yolks; the dusting adds a crisp, browned top.

The step that matters

Folding the egg whites into the mixture. Over-folding or stirring vigorously deflates the whipped egg whites, losing the air that lifts the batter. Fold gently and in portions to keep the lightness that gives the cookies their spring.
