White Sponge Cake

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Sift together the flour, cornstarch, and baking powder.

  2. Add the sugar and orange extract, then fold in the whipped egg whites.

  3. Mix thoroughly and pour into a well-buttered cake tin.

Bake

  1. Bake in a preheated oven at 400°F (200°C) for 30 minutes.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

All-purpose flour
Provides the main structure that holds the cake's crumb together as it bakes.
Cornstarch
Softens the flour's protein, giving a finer, more tender crumb.
Baking powder
Releases gas as it heats, helping the cake rise and become light.
Sugar
Sweetens the cake, adds tenderness, and helps the crust brown.
Egg whites
Trap air when whipped, giving the sponge its lift and airy structure.

The step that matters

Fold in the whipped egg whites. Whipped egg whites hold the air that lifts the sponge. Stirring them vigorously knocks out that air and makes the cake dense, so fold gently with a wide motion until just combined.

Swap the orange

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

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

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