Egg Kisses

Oven, in the book's wordsA cool oven

Ingredients

Directions

The book says “a cool oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 300°F (150°C).

  2. Beat the egg whites until stiff peaks form.

  3. Gently fold in the powdered sugar.

  4. Add vanilla extract to taste.

Shape and bake

  1. Drop tablespoonfuls of the mixture onto parchment paper, spacing them ½ inch apart.

  2. Bake until the tops are light brown.

Finish

  1. Remove from the oven, slide a knife under each kiss, and sandwich two together.

What each ingredient does

Egg whites
Whipped into stiff peaks, they trap air and give the cookies their light, airy structure.
Powdered sugar
Folded into the whipped whites, it sweetens the cookies and helps stabilize the meringue-like mixture.

The step that matters

Beating the egg whites until stiff peaks form. Egg whites must be whipped enough to hold air. Under-beaten whites produce flat, dense kisses, while over-folding after whipping deflates the foam and loses the airy texture.
