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 ↓
To Make a Spunge Cake
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
Separate the egg whites from the yolks.
Whisk the yolks for at least 1 hour.
Line a cake tin with greased paper.
Make the batter
Gradually work in the flour and a little sugar into the yolks.
Beat the egg whites until stiff and fold them into the yolk mixture gradually.
Bake
Pour the batter into the tin and grate a little sugar on top.
Bake in a 400°F (200°C) oven for 1 hour.
If the cake starts to scorch, cover it with paper.

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 yolks add richness and structure.
- Sugar
- Sweetens the cake and helps stabilise the whipped egg whites and browning on top.
- Flour
- Provides the starch structure that holds the cake once the eggs set.
- Lemon rind
- Adds aroma from the citrus oils in the zest.
The step that matters
Folding in the egg whites. Stiff whites hold the air that lifts the cake. Folding gently and gradually keeps that air in, so the batter does not deflate before baking.

- Figfits about as well
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
