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

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

  2. In a large bowl, mix the sugar and eggs with an egg beater until light and foamy.

  3. Add the lemon juice and grated rind, then carefully fold in the flour to avoid toughening the mixture.

Bake and finish

  1. On parchment paper, pipe the mixture into the shape of little fingers and sprinkle with powdered sugar.

  2. Bake in large sheet pans until done.

  3. Remove from the pans and let cool.

  4. Wet the underside of the paper to easily release the lady fingers.

  5. Once cooled, pair two flat sides together.

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

What each ingredient does

Eggs
Whipped with sugar to trap air, giving the light, foamy structure that lifts the cookies.
Flour
Provides the structure that holds the piped shapes once the eggs set in the oven.
Sugar
Sweetens the batter and helps stabilize the whipped egg foam.
Lemon juice
Adds acidity that brightens the flavor of the sweet batter.

The step that matters

Folding in the flour. Overmixing after the flour goes in knocks out the air from the whipped eggs and develops gluten, which makes the ladyfingers dense and tough. Fold gently with a spatula just until no dry flour remains.

Swap the lemon
