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 bowl, beat the eggs and gradually add the powdered sugar, mixing well.

  3. Fold in the flour and the grated lemon or orange rind until combined.

Pipe and bake

  1. Using a piping bag or a tube, pipe the mixture onto a baking sheet lined with parchment paper in strips 1 inch wide and 5 inches long.

  2. Dust the piped biscuits with fine granulated sugar.

  3. Bake for 10 to 15 minutes, until set but not browned.

Assemble

  1. Remove from the paper and brush the flat surface of one biscuit with egg white.

  2. Press a second biscuit onto the first and set aside.

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
Whipped into the batter to give the ladyfingers their light, airy structure.
Powdered sugar
Sweetens the batter and dissolves easily into the beaten eggs.
Flour
Provides the light structure that holds the piped shape while baking.
Lemon or orange rind
Adds aroma from the citrus oils to the batter.

The step that matters

Bake until set but not browned. Beaten egg foam sets as its proteins coagulate, and over-baking dries the biscuits and drives browning, making them brittle rather than soft and springy. Watch closely at the end of the time range.

Swap the lemon

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

  4. Figfits about as 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.
