Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
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 the bread
Soak the wholemeal bread in cold milk and water until soft.
Rub the soaked bread smooth.
Grate the onion and add it to the bread mixture.
Bake
Beat the egg and mix it in with the herbs, pepper, and salt.
Pour the mixture into a pie dish and place small pieces of butter on top.
Bake at 350°F (175°C) for about 30 minutes, or until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wholemeal bread
- Forms the body of the omelet and soaks up liquid to create a soft, set base.
- Egg
- Binds the mixture and sets during baking to give the omelet structure.
- Milk
- Adds moisture and richness, keeping the bread mixture tender as it bakes.
- Onion
- Adds savory flavor and moisture through the grated pulp.
- Butter
- Adds fat for richness and gentle browning on the top surface.
The step that matters
Rub the soaked bread smooth. If the bread is not fully softened and broken down, lumps remain and the texture bakes uneven. Smooth bread absorbs liquid evenly, giving a consistent set custard-like crumb.
Swap the onion
How well each one fits the dish's main ingredients (bread, milk, egg, pepper, butter):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against bread, milk, egg, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
