Lady Fingers or Naples Biscuits

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Separate the egg whites from the yolks.

Make the batter

  1. In a bowl, mix the powdered sugar and water until smooth.

  2. Add the egg yolks to the mixture and blend well.

  3. Gently fold in the flour until just combined.

  4. In a separate bowl, beat the egg whites until stiff peaks form.

  5. Carefully fold the egg whites into the batter.

Bake

  1. Drop spoonfuls of the batter onto a buttered baking pan.

  2. Bake for 10-15 minutes or until lightly golden.

Egg and flour 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
Whites whipped to stiff peaks trap air that lifts the batter, while yolks add richness and structure.
Flour
Provides structure that sets the batter as it bakes and holds the spoonfuls their shape.
Powdered sugar
Sweetens the batter and dissolves smoothly into the water for a fine, even texture.

The step that matters

Folding in the egg whites. Whipped whites are full of trapped air, and overmixing or stirring vigorously deflates them, leaving a dense, flat cookie. Fold gently and only until just combined.
