Why it works: Flour and sugar 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 (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the egg yolks until thick.
Gradually add the sugar while continuing to beat.
Add the hot water, then mix in the flour sifted with baking powder and salt.
Fold in the stiffly beaten egg whites and vinegar.
Bake
Bake for 35 minutes in a buttered and floured cake pan at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and fat, and help bind the batter together.
- Egg whites
- Whipped to stiff foam, they give the cake its light, airy structure.
- Flour
- Forms the gluten and starch framework that sets the cake's structure.
- Sugar
- Sweetens the cake and helps keep the crumb tender and moist.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Vinegar
- Its acidity helps stabilize the whipped egg white foam.
The step that matters
Folding in the egg whites. Whipped egg whites trap air that lifts the cake. Stirring them in vigorously or too long deflates the foam, leading to a dense, flat sponge. Fold gently until just combined.
