Genoa Cake

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.

Prepare

  1. Blanch the almonds and cut them into pieces.

  2. Wash the currants and clean the sultanas.

Make the batter

  1. Beat the butter until creamy, then add the sugar and beat until light.

  2. Add the flour and beat in the eggs one by one.

  3. Stir in the fruit and baking powder.

Bake and finish

  1. Line a shallow pan with parchment paper and pour in the mixture.

  2. Bake in a moderate oven at 350°F (175°C) for 1 to 1.5 hours.

  3. When cooked, brush the top of the cake with egg white and sprinkle with chopped almonds.

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

What each ingredient does

All-purpose flour
Provides the starch and gluten network that gives the cake its structure.
Butter
Adds richness and a tender crumb, and holds air when creamed with sugar.
Eggs
Bind the batter, add structure as they set, and contribute moisture and richness.
Caster sugar
Sweetens the cake, and creaming it with butter traps air that lightens the texture.
Baking powder
Releases gas in the oven, helping the cake rise and become lighter.

The step that matters

Beating in the eggs one by one. Adding eggs gradually lets them emulsify fully into the creamed butter and sugar. Adding them too quickly can cause the batter to curdle and lose the trapped air needed for a good rise.
