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 ↓

Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Beat the sugar and egg yolks for 20 minutes.
Add the flour and beaten egg whites until stiff.
Bake in a moderate oven (350°F / 175°C) for 45-60 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites and yolks provide structure and lift, giving the cake its airy, sponge-like crumb.
- Sugar
- Beaten with the yolks to build a stable base and add sweetness and tenderness.
- Hungarian flour
- Forms the set structure of the cake once heated, holding the risen foam in shape.
The step that matters
Folding the flour into the whites. Overmixing knocks air out of the beaten egg whites, so the cake rises less and turns dense. Fold gently, just until no streaks of flour remain.
