Citron Pound Cake

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

  1. Cream the butter and sugar together until light and fluffy.

  2. Add the egg yolks and mix well.

  3. Gradually add the flour and mix until combined.

  4. Whip the egg whites until stiff peaks form, then gently fold them into the batter.

Layer and bake

  1. In a cake pan, place a layer of batter and sprinkle thickly with citron.

  2. Repeat layering with batter and citron until the pan is filled.

  3. Bake in a slow oven at 300°F (150°C) for 1½ to 2 hours.

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

What each ingredient does

Eggs
Yolks enrich the batter, and whipped whites lighten it and give the cake its structure.
Butter
Creamed with sugar, it traps air and adds richness and a tender crumb.
Flour
Forms the structure of the cake as it sets in the oven.
Sugar
Sweetens the cake and, creamed with butter, helps hold air for a light texture.
Citron
Provides the characteristic aromatic flavor and tart, chewy bits throughout the cake.

The step that matters

Folding in the egg whites. Whites beaten to stiff peaks hold the air that lifts the cake. Folding gently keeps that air in; vigorous stirring deflates the batter and leaves a dense cake.
