Why it works: Pepper and parsley 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 says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Butter a baking tin.
Assemble
Lay slices of cheese in the tin.
Sprinkle pepper and salt over the cheese.
Break in the eggs on top.
Cover with bread crumbs and add oiled butter.
Bake and serve
Bake for 12 to 15 minutes.
Sprinkle minced parsley over before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a firm custard-like layer that holds the dish together when baked.
- Cheese
- Melts into a rich, gooey base that binds with the eggs.
- Bread crumbs
- Crisp and brown on top, adding texture against the soft eggs.
- Oiled butter
- Adds fat that helps the crumbs brown and enriches the flavour.
The step that matters
Breaking in the eggs. Eggs should sit whole on top of the cheese so their whites set around the yolks. Breaking them carefully keeps the yolks intact and prevents the whites from spreading and overcooking unevenly.
Swap the parsley
How well each one fits the dish's main ingredients (egg, cheese, pepper, butter, bread):
- Parsleythe original
- Nutmegfits about as well
- Thymefits less well
- Sagefits less well
Fit is the average pairing score against egg, cheese, pepper, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
