Orange Layer 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.

Make the batter

  1. Preheat the oven to 350°F (175°C).

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

  3. Add the water and mix well.

  4. Gradually add the flour and baking powder, mixing until smooth.

Bake the layers

  1. Divide the batter into layers and bake until golden.

Make and fill the cake

  1. In a bowl, mix the egg yolk, orange juice, and powdered sugar.

  2. Beat the egg whites until stiff peaks form, then fold into the orange mixture.

  3. Spread the orange filling between the baked layers.

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

What each ingredient does

Butter
Creaming with sugar traps air and makes the crumb tender and rich.
Sugar
Sweetens the cake, helps browning, and works with butter to create a light texture.
Flour
Forms the structure that holds the cake's layers together.
Eggs
Add structure and richness, and the whites give the filling lightness when beaten.
Baking powder
Releases gas in the batter, helping the layers rise and stay light.
Orange juice
Adds bright acidity and citrus flavour to the filling.

The step that matters

Folding the beaten egg whites into the orange mixture. Beaten whites trap air that gives the filling its lightness. Folding gently, rather than stirring, preserves that air so the filling does not collapse or turn dense.

Swap the orange

How well each one fits the dish's main ingredients (butter, sugar, flour, egg):

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Orangethe original

Fit is the average pairing score against butter, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
