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. Beat the egg yolks and sugar together.

  3. Beat the egg whites to a stiff froth.

  4. Gently stir in the flour without overmixing.

Pipe and dust

  1. Make a funnel-shaped bag from canvas with a ½ inch diameter tube.

  2. Pipe the mixture onto parchment paper in finger shapes.

  3. Dust lightly with powdered sugar.

Finish

  1. Once baked and cooled, wet the paper.

  2. Remove the lady-fingers from the paper easily.

  3. Stick two lady-fingers together back to back while moist.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: 2-nonenal (fatty, green).

Flour and egg 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 whites trap air, giving the sponge its light, airy structure.
Flour
Forms the gluten network that gives the lady-fingers their set structure.
Sugar
Sweetens the batter and, beaten with the yolks, helps build a stable foam.

The step that matters

Gently stir in the flour without overmixing. Overmixing develops too much gluten, making the lady-fingers tough, and it also deflates the whipped egg whites, reducing the airy rise.
