Butter Sponge-cake

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the batter

  1. Cream the butter and ½ cup of sugar together.

  2. Beat the egg yolks with the remaining sugar until light.

  3. Stir the creamed butter and sugar into the yolk mixture.

  4. Beat the egg whites until stiff.

  5. Fold the stiff egg whites into the batter.

  6. Slowly stir in the flour.

  7. Add lemon zest.

Bake

  1. Pour the batter into a prepared cake pan.

  2. Bake for 25-30 minutes.

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

What each ingredient does

Eggs
Egg whites whipped to stiff peaks give the cake its light, airy structure, while yolks add richness.
Butter
Creamed with sugar, butter adds fat that gives a tender crumb and rich flavour.
All-purpose flour
Flour provides the starch that sets during baking, giving the cake its structure.
Sugar
Sugar sweetens the cake and helps hold air when creamed and beaten into the batter.

The step that matters

Fold the stiff egg whites into the batter. Whipped egg whites trap air that leavens the cake. Folding gently, rather than stirring, keeps that air in the batter so the cake rises light instead of dense.

Swap the lemon

How well each one fits the dish's main ingredients (egg, sugar, flour, butter):
