Newport Orange and Lemon 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 together the sugar and butter until light and fluffy.

  3. Add the milk and mix well.

  4. In a separate bowl, combine the flour and baking powder.

  5. Gradually add the flour mixture to the creamed mixture, mixing until smooth.

  6. Beat in the eggs one at a time, then add the lemon juice and grated rind.

  7. Pour the batter into jelly cake tins and bake until golden.

Make the filling and icing

  1. For the filling, beat the egg whites until stiff, then mix in the granulated sugar, orange rind, juice, and pulp, and lemon juice.

  2. For the icing, beat the egg whites until stiff, then mix in the powdered sugar, orange rind, juice, and lemon juice.

Assemble

  1. Spread the filling between the layers of cooled cake.

  2. Spread the icing between each layer when cool.

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

What each ingredient does

Butter
Creams with the sugar to trap air and give the cake a tender, rich crumb.
Flour
Forms the structure that holds the cake's shape as it bakes.
Eggs
Add structure and richness, and help bind the batter.
Baking powder
Releases gas during baking so the cake rises and becomes light.
Sugar
Sweetens the cake and helps it brown and stay moist.
Egg whites
Beaten until stiff to give the filling and icing a light, airy structure.

The step that matters

Beating the egg whites until stiff for the filling and icing. Egg whites must be beaten to stiff peaks to trap air that gives the filling and icing lightness. Under-beaten whites stay runny and collapse, while over-beaten whites turn dry and grainy.
