Citron Cake

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 egg whites and yolks separately.

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

  3. Add the egg yolks and sweet milk, mixing well.

  4. Sift together the flour and baking powder, then gradually add to the mixture.

  5. Fold in the beaten egg whites and the chopped citron.

Bake

  1. Pour the batter into long, narrow pans.

  2. Bake until a toothpick inserted in the center comes out clean.

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

What each ingredient does

Eggs
Whites beaten separately and folded in add lightness and help the cake rise and hold its structure.
Butter
Creamed with sugar to trap air, giving the cake a tender, fine-textured crumb and rich flavor.
Sugar
Creamed with butter to aerate the batter and adds sweetness and tenderness to the crumb.
Flour
Provides the main structure that sets the cake as the batter bakes.
Baking powder
Releases gas during baking so the cake rises and becomes light.
Citron
Chopped citron rolled in flour adds candied fruit flavor and chewy pieces throughout the cake.

The step that matters

Folding in the beaten egg whites. Egg whites hold air from beating. Stirring them in too hard deflates that air, so the cake bakes up denser and less light.
