Genoese Pastry

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.

Make the batter

  1. In a basin, combine eggs and sugar, then whip over hot water for about 25 minutes until thick and creamy.

  2. Melt the butter and sift in the flour, then add a few drops of flavoring. Mix the ingredients very lightly.

Bake and serve

  1. Pour the mixture into a well-greased shallow round tin lined with buttered paper.

  2. Bake for 30 minutes at 350°F (175°C).

  3. Cut into shapes and layer with fruit or jam, then cover with whipped cream.

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

What each ingredient does

Eggs
Whipped with sugar, they trap air that gives the sponge its light structure.
Flour
Sifted in last, it provides the set structure that holds the whipped foam together.
Butter
Melted in, it adds richness and tenderness to the crumb.
Castor sugar
Whipped with the eggs, it stabilizes the foam and adds sweetness.

The step that matters

Mix the ingredients very lightly. Folding gently keeps the air bubbles from the whipped eggs intact. Overmixing deflates the foam, leading to a dense, flat sponge.
