Sponge Cookies

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).

Make the batter

  1. Beat the eggs with the sugar until very light.

  2. Gently fold in the flour and baking powder.

Bake

  1. Drop spoonfuls of the mixture onto a well-buttered pan.

  2. Bake until the cookies are light brown.

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

What each ingredient does

Eggs
Whipped into a foam that traps air, giving the cookies their light, sponge-like structure.
Sugar
Sweetens the cookies and helps stabilize the whipped egg foam.
Flour
Provides the starch and protein that set into the cookie's structure as it bakes.
Baking powder
Releases gas in the batter, helping the cookies rise in the oven.

The step that matters

Fold in the flour and baking powder gently. Vigorous stirring knocks out the air whipped into the eggs and sugar, which makes the cookies flat and dense instead of light.
