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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Beat the eggs until frothy.
Dissolve a little volatile salts in ½ cup hot water and let it cool.
Mix the cooled water with the beaten eggs and beat for 10 minutes.
Add the grated sugar and flour, and beat well together.
Add a few seeds.
Bake
Bake in a hot oven at 400°F (200°C) 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 into a foam that traps air, giving the cake its light, risen structure.
- Fine flour
- Sets during baking to form the cake's framework and hold its shape.
- Loaf sugar
- Adds sweetness and helps stabilise the beaten egg foam while the batter is mixed.
The step that matters
Beat the eggs and water well. The air whipped into the eggs expands in the oven and gives the sponge its lift. Under-beating leaves it dense, while deflating the foam when adding the flour and sugar loses that air.
“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.
