Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Diet-bread Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Boil the water and loaf sugar together, then skim off any impurities.
Beat the eggs very finely, leaving out half the whites.
Make the batter
Pour the boiled sugar into the beaten eggs and whisk for at least 15 minutes.
Gently stir in the fine flour until well combined.
Bake and serve
Grease square tins and line them with white paper, filling them three-quarters full.
Sprinkle loaf sugar on top and bake in a 400°F (200°C) oven.
Once baked, remove the cakes from the molds while hot.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Whisked into the batter to trap air and give the cake its structure as they set.
- Fine flour
- Forms the cake's main structure once its starches set in the oven.
- Loaf sugar
- Sweetens the cake and helps give it a fine, tender crumb.
The step that matters
Whisking the eggs and sugar. Whisking the boiled sugar into the eggs for a long time traps air that leavens the batter. Under-whisking leaves a dense cake, so the batter needs to be well aerated before the flour is folded in gently to keep that air.
