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 ↓
Egg Cutlets
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the eggs
Split the hard-cooked eggs lengthwise and sprinkle with bread crumbs and lumps of butter.
Heat the eggs in a slow oven at 300°F (150°C) until warmed through.
Make the sauce
In a saucepan, heat the milk and water over boiling water.
Add the minced onion, tomatoes, and parsley to the saucepan and cook.
Season with butter and add the chopped green pepper.
Strain the mixture and thicken with flour.
Serve
Pour the sauce over the eggs and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard cooked eggs
- Form the main body of the dish, providing protein-rich bulk that holds the sauce.
- Bread crumbs
- Absorb butter and moisture on the eggs, giving a softer coating texture.
- Butter
- Adds richness and fat that carries flavour and helps the crumbs brown lightly.
- Flour
- Thickens the strained sauce so it coats the eggs rather than running off.
- Tomatoes
- Provide acidity and body to the sauce, balancing the richness of the butter and milk.
The step that matters
Thicken the sauce with flour. Flour must be cooked into the liquid to avoid lumps and raw starch taste; it thickens as starch granules swell with heat, so the sauce needs enough time at a simmer to reach a coating consistency.
Swap the onion
How well each one fits the dish's main ingredients (egg, bread, butter, milk, tomato, parsley, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against egg, bread, butter, milk, tomato, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
