Good Plain 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. Weigh the eggs, then use the same weight of powdered sugar and the weight of 3 eggs in all-purpose flour.

Make the batter

  1. Whisk the eggs well, add the sugar and lemon flavoring, and beat again.

  2. Sift the flour and baking powder together, add them gradually to the mixture, and mix everything quickly.

Bake

  1. Bake in a preheated oven at 350°F (175°C) for 1 to 1.5 hours.

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

What each ingredient does

Eggs
Whisked eggs trap air and provide structure, moisture and setting as the cake bakes.
Powdered sugar
Adds sweetness and helps give the cake a fine, tender crumb.
All-purpose flour
Its proteins form gluten, which gives the cake its structure once baked.
Baking powder
Releases gas when moistened and heated, helping the cake rise.
Lemon essence or grated lemon rind
Provides the lemon aroma that flavors the cake.
Lemon juice
Adds a little acidity and brightness to the flavor.

The step that matters

Add the flour gradually and mix quickly. Flour should be folded in gently and briefly. Overmixing develops too much gluten, making the cake tough, and it can deflate the air whisked into the eggs, which the cake needs to rise.

Swap the lemon
