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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Boil the sugar until it threads.
Pour the hot sugar slowly over the well-beaten egg whites.
Add the egg yolks and mix well.
Sift the flour with the baking powder and fold it into the mixture.
Bake
Bake in a moderate oven at 350°F (175°C) until golden.

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
- Egg whites
- Whipped to foam, they trap air that gives the cake its light, airy structure.
- Egg yolks
- Add richness and tenderness, and help bind the batter.
- Granulated sugar
- Sweetens the cake and, boiled to a thread, stabilises the whipped egg whites.
- Flour
- Provides the structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise.
The step that matters
Pouring the hot sugar over the egg whites. The sugar must be poured slowly in a thin stream while whisking, so the hot syrup cooks and stabilises the foam without deflating it. Pouring too fast or too cold can collapse the whites and leave a dense cake.
“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.
