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 mixture
Soak the wholemeal bread in cold milk and water until soft.
Rub the soaked bread smooth.
Mix in the grated onion, beaten egg, flavoring herbs, pepper, and salt.
Bake
Transfer the mixture to a pie dish.
Dot the top with small pieces of butter.
Bake at 350°F (175°C) for about 4 hours, 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
- Soaked and rubbed smooth, it forms the body and soft texture of the omelet.
- Egg
- Sets as it bakes, binding the bread and onion into a firm, sliceable custard.
- Milk
- Softens the bread and adds moisture and a tender crumb.
- Onion
- Adds savory aroma and sweetness as it cooks into the mixture.
- Butter
- Adds fat that enriches flavor and promotes gentle browning on the top.
The step that matters
Bake until done. The egg must set fully through the center, so the omelet is cooked to the middle and not left wet or custardy. Baking for the stated time at moderate heat sets the egg gradually, which helps avoid a dry edge while the center is still runny.
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.
