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 ↓
Savoy or Spunge Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Weigh 12 eggs and balance their weight with sugar.
Remove half of the sugar and balance the remaining half with flour.
Separate the egg whites from the yolks and whip the whites until very light.
Gently mix the whipped egg whites with the yolks.
Sift in the sugar and flour alternately until both are used.
Add grated lemon peel and mix well.
Bake
Pour the batter into paper cases or small tin molds.
Bake at 350°F (175°C) until golden and set.

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, giving the cake its light, airy structure.
- Sugar
- Sweetens the cake and helps stabilise the whipped egg whites.
- All-purpose flour
- Provides the starch that sets during baking to hold the cake's structure.
The step that matters
Whipping the egg whites. Whites must be whipped until very light so they hold air. Deflating them when folding in the yolks, flour and sugar will leave a dense cake instead of a light one.

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