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 the mixture is thick and creamy.

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

Bake

  1. Prepare a well-buttered and papered baking tin.

  2. Pour the mixture into the tin and bake 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
Whisked to trap air, giving the pastry its light, sponge-like structure.
Fine flour
Provides the set structure once the egg foam is baked.
Butter
Adds richness and a tender crumb to the finished pastry.
Castor sugar
Sweetens the batter and helps stabilise the whisked egg foam.

The step that matters

Whisking the eggs and sugar over water. Warming the eggs and sugar helps them whisk to a thick, stable foam. Whisking until thick and creamy traps the air that gives the sponge its lift, so stopping early leaves a dense result.
