Golden Sponge Cake

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.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the batter

  1. Beat the egg whites until very stiff.

  2. Beat the yolks until the bubbles look fine.

  3. Add the sugar to the yolks and beat until dissolved.

  4. Gently fold in the beaten egg whites.

  5. Add the flour and mix until combined.

Bake

  1. Pour the batter into greased brick-shaped tins.

  2. For a better texture, line the tins with a paste made from flour and water, rolled out like pie crust.

  3. Bake for nearly an hour.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.

What each ingredient does

Eggs
Whipped whites trap air, giving the sponge its light, airy structure.
Sugar
Dissolved into the yolks, it sweetens the cake and helps give it a tender crumb.
Flour
Its proteins set during baking, giving the cake its firm structure.

The step that matters

Gently fold in the beaten egg whites. Folding keeps the air whipped into the egg whites. Stirring or deflating them vigorously would knock out air bubbles, leaving a denser cake.
