Okange Cake, with Icing

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

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

  2. Beat the 4 eggs thoroughly.

  3. Rub the cream of tartar into the flour.

  4. Dissolve the baking soda in a little of the milk.

  5. Cream the butter and sugar together.

  6. Add the eggs, flour, and milk to the butter mixture and mix well.

Bake and ice

  1. Pour the batter into Washington pie plates.

  2. Bake until golden.

  3. Beat the egg whites to stiff peaks.

  4. Gradually add the powdered sugar, orange zest, orange juice, and lemon juice, mixing until smooth.

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

What each ingredient does

Eggs
Bind the batter and add structure and richness as the cake sets.
Butter
Adds fat for tenderness and flavor in the batter.
Flour
Provides the structure that holds the cake together as it bakes.
Cream of tartar
Acidifies the batter and helps the baking soda react and lift the crumb.
Baking soda
Reacts with the acid in the batter to produce gas that makes the cake rise.
Egg whites
Whipped to stiff peaks, they give the icing a light, airy texture.

The step that matters

Dissolve the baking soda fully before mixing. Baking soda must be evenly dispersed in the liquid so it reacts with the acid in the batter. Clumps leave pockets of bitter residue and uneven rising.

Swap the orange

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