Cream Sponge Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate 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. Mix the sugar with the lemon rind and juice.

  3. Separate the eggs.

  4. Beat the yolks and add the sugar mixture. Beat until pale yellow and thick.

  5. Beat the egg whites until stiff. Gently fold them into the batter.

  6. Sift in the flour a small portion at a time, folding carefully.

Bake and finish

  1. Pour the batter into a square pan and bake for 30 to 45 minutes.

  2. Remove from the oven and cool.

  3. Cut the cake in half and fill with orange cream filling.

  4. Top with Orange Water Icing or sprinkle with sifted powdered sugar.

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

What each ingredient does

Eggs
Whipped whites trap air, giving the sponge its light, airy structure while the yolks add richness.
All-purpose flour
Provides the starch and gluten that set the cake's structure as it bakes.
Granulated sugar
Sweetens the batter and helps the yolks whip to a thick, stable foam.
Lemon
Rind and juice add aroma and a touch of acidity that brightens the sweet sponge.

The step that matters

Folding the whites and flour into the batter. Whipped whites and flour deflate easily when stirred vigorously. Gentle folding keeps the trapped air, which is what makes the sponge rise and stay light.

Swap the lemon

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

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