Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ingredients
Directions
The book says “a very slack oven”. The 300°F in the steps is the modern equivalent, not the book's own figure.
Assemble the cake
Cut the sponge cake into half‑inch slices.
Cover each slice with a different kind of preserve.
Reassemble the cake in its original form.
Ice and dry
Whisk the egg whites until stiff peaks form.
Spread the whipped egg whites over the cake.
Sift more powdered sugar over the icing.
Place the cake in a very cool oven (300°F / 150°C) to dry.

What each ingredient does
- Sponge cake
- Provides the light, porous structure that holds the layers and preserves together.
- Various preserves
- Add sweetness, fruit flavour and moisture between the cake slices.
- Egg whites
- Whipped into a foam that forms a light coating which sets and dries in the oven.
- Powdered sugar
- Adds sweetness and a fine, dry sugar layer over the egg white topping.
The step that matters
Drying in a very cool oven. Whipped egg whites are delicate and sugar-rich. A very low oven dries the coating slowly so it sets without browning or weeping. Higher heat would brown the surface and could leave the foam collapsed or wet inside.
