Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. 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
Soak the bread in the milk.
In a skillet, melt 1½ oz. of butter and fry the onion until soft.
Mix the fried onion with the soaked bread.
Bake
Add the herbs, parsley, and seasoning, and mix well.
Butter a pie dish with the remaining butter.
Pour the mixture into the pie dish and bake at 350°F (175°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Soaked in milk, it softens and gives the omelet a light, custardy body.
- Eggs
- Set when heated, binding the mixture and giving it structure.
- Milk
- Soaks into the bread and adds moisture to keep the bake tender.
- Butter
- Adds fat for richness and flavour, and helps the onion brown lightly.
- Onion
- Softened by frying, it adds sweetness and savoury depth.
The step that matters
Bake until set. Eggs set as their proteins coagulate with heat. Pulling the dish too early leaves a runny centre, while overbaking makes the eggs tight and rubbery.
Swap the onion
How well each one fits the dish's main ingredients (bread, milk, parsley, egg, butter, pepper):

- Asparagusfits better
- Onionthe original
Fit is the average pairing score against bread, milk, parsley, egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
