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 ↓
Dream Sponge Cake
Ingredients
Directions
The book says “a 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).
Beat the egg whites and yolks separately.
Make the batter
Add the sugar, salt, flour, and baking powder to the beaten yolks and mix well.
Gently fold in the beaten egg whites.
Finally, add the cold water and mix until combined.
Bake
Pour the batter into a prepared cake pan and bake in the oven.

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
- Beaten whites trap air, giving the cake its light, risen structure.
- Flour
- Forms the gluten network that sets the cake's crumb once baked.
- Sugar
- Sweetens the cake and helps keep the crumb tender.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Cold water
- Adds moisture to the batter, loosening it for a softer crumb.
The step that matters
Gently fold in the beaten egg whites. Whipped egg whites hold air that makes the sponge rise. Stirring vigorously or overmixing deflates the foam, leaving a dense, flat cake. Use a light folding motion until just combined.
