Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

Light Sponge Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the eggs and syrup

  1. In a bowl, whisk the eggs for 1-2 minutes.

  2. In a saucepan, boil the sugar and water.

  3. Once boiling, pour the mixture into the eggs while whisking continuously.

Make the batter

  1. Whisk for 15 minutes, then gently stir in the sifted flour until just mixed.

  2. Add flavoring as desired.

Bake

  1. Pour into a well-buttered and floured cake tin.

  2. Bake in a quiet oven at 300°F (150°C) until ready.

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.

    Shared aroma: 2-nonenal (fatty, green).

Flour and egg 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
Whisked into a foam that traps air, giving the cake its light, risen structure.
Sugar
Sweetens the cake and helps stabilize the whisked egg foam.
Fine flour
Forms the cake's structure as its proteins and starches set in the oven.
Egg yolks
Add richness and fat, giving a tender, moist crumb.

The step that matters

Folding in the flour. The flour must be stirred in gently and only until just mixed. The whisked egg foam holds the cake's rise, and overmixing deflates it, producing a dense, heavy crumb.
