Why it works: Flour and egg are a kitchen classic. They rank in the top 8% of all ingredient pairs, and 104,138 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. The science ↓
The recipe
Ingredients
Contains: egg, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, combine the flour, beaten eggs, sugar, and rose or orange-flower water.
Beat the mixture thoroughly until well combined.
Bake
Pour the batter into a baking dish and bake for 1 hour.

Flour and egg share little aroma chemistry, yet 104,138 recipes mention both: they likely 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
- Provide structure and moisture as they set, holding the cake together.
- Flour
- Forms the main structure of the cake as the batter sets in the oven.
- Sugar
- Adds sweetness and helps the cake brown lightly as it bakes.
The step that matters
Beat the mixture thoroughly until well combined. Thorough beating blends the eggs, sugar and flour evenly and traps air in the batter, so the cake bakes with a uniform, light crumb instead of dense pockets.
