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 rather slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
Beat the eggs and sugar together until creamy, light, and white.
Add the flavoring and cold water, then beat again.
Gently fold in the sifted flour and baking powder.
Bake
Pour the batter into a deep tin and bake until done.

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 with sugar to trap air, giving the cake its light, airy structure.
- Sugar
- Beaten with the eggs to help build a stable foam and add sweetness.
- Sifted flour
- Provides the starch that sets during baking to form the cake's structure.
- Baking powder
- Releases gas in the batter so the cake rises and becomes tender.
The step that matters
Folding in the flour and baking powder. Folding gently keeps the air bubbles from the whipped eggs intact. Overmixing deflates the batter, so the cake bakes up dense instead of light.
