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 gentle oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Weigh the eggs and use their weight in sugar.
Make the batter
Beat the egg yolks with the flour.
Whisk the egg whites until stiff.
Gradually mix the egg whites and flour with the yolk mixture.
Beat well for 30 minutes.
Bake
Bake in a 400°F (200°C) oven for 1 hour.

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 for lift, while the yolks add richness and help set the crumb.
- Sugar
- Adds sweetness and helps stabilise the whipped egg whites.
- Flour
- Its starch and proteins set during baking to give the cake its structure.
The step that matters
Gradually mix the egg whites and flour into the yolk mixture. Whipped egg whites hold air that makes the cake rise. Folding gently and gradually keeps that air in; vigorous stirring knocks it out, leaving a denser, flatter cake.
