Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Sift the flour through a fine sieve.

  2. Melt the butter in a pan.

Make the batter

  1. In a bowl, whisk the eggs and sugar over hot water for 25 minutes.

  2. Gradually add the flour and melted butter alternately, stirring gently until combined.

Bake

  1. Line a shallow baking tin with buttered paper and pour the mixture into it.

  2. Bake in a preheated oven at 400°F (200°C) for 30 minutes.

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

What each ingredient does

Eggs
Whisked with sugar to trap air, giving the sponge its light, airy structure.
Flour
Provides the starch that sets during baking, giving the sponge its structure.
Butter
Adds richness and a tender crumb when folded in after melting.
Fine sugar
Sweetens the batter and helps stabilise the whisked eggs for volume.

The step that matters

Whisking the eggs and sugar over hot water. The eggs must be whisked until thick and pale so they hold a large amount of trapped air. Gentle heat helps the foam form and thicken. Under-whisking leads to a flat, dense sponge, while folding too vigorously knocks out the air.
