Loaf 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 yolks until light.

  2. Add the granulated sugar and mix well.

  3. Sift the flour with the baking powder and add it to the mixture.

  4. Gently fold in the beaten egg whites.

  5. Beat the entire mixture for five minutes.

Bake

  1. Pour the batter into a loaf pan and bake for 20 minutes.

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

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

What each ingredient does

Egg whites
Trap air when beaten, giving the cake its light, airy lift and structure.
Egg yolks
Add richness and moisture, and help the batter set tender.
Flour
Forms the gluten and starch network that gives the cake its structure.
Baking powder
Releases gas in the batter, causing the cake to rise.
Granulated sugar
Sweetens the cake and helps keep the crumb tender.

The step that matters

Gently fold in the beaten egg whites. Egg whites hold air bubbles that make the cake light. Stirring or mixing hard deflates them, so the batter loses its rise and becomes dense. Use a light, sweeping motion until just combined.
