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.
Make the batter
Beat the eggs until frothy.
Dissolve the volatile salts in the 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.
Fold in 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
- Beaten eggs trap air that gives the sponge its light, airy structure.
- Volatile salts
- Release gas as they heat, helping the batter rise and become lighter.
- Hot water
- Dissolves the volatile salts and adds moisture to the batter.
- Loaf sugar
- Sweetens the cake and helps the batter hold its beaten air.
- Fine flour
- Sets during baking to form the cake's structure.
The step that matters
Beating the eggs and water. The air beaten into the eggs is the main source of lift in a sponge. Beat thoroughly before adding the flour, then fold gently so the air is not knocked out.
