Genoese Pastry or Cake

Oven, in the book's wordsA moderately hot oven

Ingredients

Directions

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

Prepare

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

  2. Dry and sift the flour.

  3. Separate the egg whites from the yolks.

Make the batter

  1. Add the sugar to the yolks and beat vigorously until thick and creamy.

  2. Stir in the melted butter.

  3. Whip the egg whites to stiff peaks.

  4. Gently fold the flour into the egg whites.

  5. Combine the egg white mixture with the yolk mixture, mixing lightly but thoroughly.

Bake

  1. Pour the batter into a greased and lined cake tin.

  2. Bake for about 1 hour.

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 that lifts the cake, and yolks add richness and structure.
Fine flour
Starch sets during baking, giving the sponge its structure once the eggs have expanded.
Castor sugar
Sweetens the batter and helps the yolks thicken and become creamy when beaten.
Butter
Adds fat that softens the crumb and gives a richer flavour.

The step that matters

Gently fold the flour into the egg whites. Whipped egg whites hold air bubbles that make the sponge rise. Vigorous stirring knocks that air out, so the cake turns out dense and flat.
