Sponge Jelly 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.

Prepare

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

  2. Beat the egg whites and yolks separately.

Make the batter

  1. Mix the sugar, flour, and baking powder together.

  2. Add the boiling water to the dry ingredients and mix well.

  3. Fold in the beaten egg whites gently.

Bake and assemble

  1. Pour the batter into jelly tins and bake until golden.

  2. Cool and layer with jelly or chocolate frosting between the cakes.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

Eggs
Whipped whites trap air for lift, while the yolks add richness and structure.
Flour
Its proteins set during baking to give the cake its structure.
Sugar
Adds sweetness and helps the cake brown and stay tender.
Baking powder
Releases gas in the batter, making the sponge rise.

The step that matters

Fold in the beaten egg whites gently. Whites hold the air that makes the sponge light. Stirring vigorously knocks that air out, so the cake bakes up dense and flat instead of airy.
