Sponge Roll

Oven, in the book's wordsA fairly hot oven

Ingredients

Directions

The book says “a fairly hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

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

  2. In a bowl, mix the flour, sugar, and baking powder.

  3. Add the melted butter and warm milk to the dry ingredients. Stir until well combined.

  4. Pour the batter into a greased baking dish.

Bake

  1. Bake for 20-25 minutes or until golden brown.

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

What each ingredient does

Flour
Forms the main structure of the batter as its proteins set during baking.
Sugar
Adds sweetness and helps the crust brown during baking.
Baking powder
Releases gas in the batter so the cake rises and becomes light.
Butter
Adds fat for tenderness and richness in the crumb.
Milk
Adds moisture and hydrates the flour to form the batter.

The step that matters

Bake until golden brown. Baking time depends on oven accuracy and pan size. Pulling the cake too early can leave the centre wet and sunken, while baking too long dries it out. Check for golden colour and a set centre.
