Genoese Pastry

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.

Make the batter

  1. Beat the eggs and sugar together for about 20 minutes until creamy.

  2. Rub the butter lightly into the flour.

  3. Gently stir the flour into the beaten eggs without overmixing.

Bake

  1. Pour the mixture into a greased shallow cake tin.

  2. Bake at 350°F (175°C) 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
Trap air when beaten, giving the sponge its light, airy structure.
Flour
Provides the framework that sets the crumb as the batter bakes.
Butter
Adds fat for a tender texture and richer flavour.
Castor sugar
Adds sweetness and helps stabilise the air trapped in the beaten eggs.

The step that matters

Gently stirring the flour into the beaten eggs. The batter depends on the air beaten into the eggs. Overmixing knocks out that air and develops gluten in the flour, which makes the sponge dense and tough instead of light.
