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

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
- Boiled eggs form the bulk of the filling and set into a soft, sliceable body when baked.
- Milk
- Adds moisture to the dish, helping the filling stay tender as it bakes.
- Butter (in the method)
- Adds richness and fat, helping the top brown lightly as it bakes.
- Bread crumbs (in the method)
- Absorb moisture and give the filling a soft, binding texture.
- Onion
- Adds a sharp, aromatic flavour that complements the eggs.
The step that matters
Bake twenty minutes. Baking too long dries out and toughens the egg filling, since egg proteins set and squeeze out moisture when overcooked. Keep the milk covering to hold moisture.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (flour, sugar, egg, cream cheese, cheese, rum, milk):

- Onionthe original
Fit is the average pairing score against flour, sugar, egg, cream cheese, cheese, rum, milk. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
