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 ↓
Small Spunge Biscuits
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 the batter
Separate the egg whites from the yolks.
Beat the yolks well, then beat the whites until stiff and white.
Grate the lemon rind and combine it with the sugar and egg yolks.
Gently fold in the flour.
Bake
Spoon the mixture into small tins and sprinkle fine sugar on top.
Bake in a 400°F (200°C) oven until golden.
If the tops scorch, cover 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, giving the biscuits their light, spongy structure.
- Loaf sugar
- Sweetens the batter and helps the crumb brown as it bakes.
- Flour
- Provides the set structure that holds the sponge once it bakes.
The step that matters
Gently fold in the flour. Heavy stirring knocks air out of the whipped whites, so the biscuits bake flat and dense instead of light and spongy.

How well each one fits the dish's main ingredients (egg, sugar, flour):

- 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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
