Genoise Cake {Genoese Mixture for Gateaux, Etc.}

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

In a warm bowl, cream the butter with a wooden spoon until smooth.
Add the lemon rind and sugar, and beat until the mixture is white, about 15 minutes.
Stir in the egg yolks one at a time.
Fold in the sifted flour gently.

Bake

Pour the batter into a prepared cake pan and bake at 350°F (175°C) until golden and a toothpick comes out clean.

Recipe from a historical cookbook (Internet Archive).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Butter: Creamed with sugar to trap air, giving the cake a tender, rich crumb.
Eggs: Provide structure and lift as the batter sets in the oven.
Sifted flour: Forms the cake's structure once heated and set.
Castor sugar: Helps aerate the creamed butter and adds sweetness and golden browning.

The step that matters

Folding in the flour. Folding gently keeps the air beaten into the batter. Stirring vigorously develops gluten, which can make the cake dense and tough.
