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. Break the eggs into a bowl and add the sugar.

  2. Place the bowl over a saucepan of boiling water and whisk until lukewarm.

  3. Remove the bowl and continue whisking until thick and creamy.

  4. Add the melted butter and gently stir in the sifted flour.

Bake

  1. Pour the mixture into a well‑buttered and lined baking tin.

  2. Bake in a moderate oven at 350°F (175°C) until golden.

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

What each ingredient does

Eggs
Whipped to trap air, giving the cake its light, airy structure.
Fine flour
Provides the starch that sets during baking, forming the cake's structure.
Butter
Adds richness and a tender crumb, and helps the cake brown.
Castor sugar
Sweetens the batter and helps stabilise the whisked egg foam.

The step that matters

Whisking the eggs and sugar over hot water. Warming the eggs and sugar lets the sugar dissolve and the foam thicken more fully. Whisking until thick and creamy before adding the flour creates the air that gives the sponge its lift.
