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 ↓
Deviled Macaroni
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the macaroni
Boil the macaroni in salted water for 25 minutes.
Drain the macaroni and chop finely.
Make the sauce
Melt the butter in a saucepan. Mix in the flour.
Add the milk and stir until boiling.
Press the hard-boiled yolks and whites through a sieve. Add the pressed yolks and whites to the saucepan.
Stir in the chopped parsley, red pepper, sweet Spanish pepper, nutmeg, and grated onion.
Mix well with the macaroni.
Bake and serve
Place the mixture into individual shells or cases.
Cover with bread crumbs moistened with melted butter.
Brown in a 400°F (200°C) oven.
Serve with tomato ketchup or chili sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and gives it a firm, chewy body.
- Butter
- Enriches the sauce and helps the bread crumbs brown on top.
- Flour
- Thickens the milk into a smooth white sauce that binds the dish.
- Milk
- Forms the liquid base of the sauce, giving it creaminess.
- Hard-boiled eggs
- Add richness and body to the sauce as their yolks and whites are pressed in.
The step that matters
Bringing the milk to a boil while stirring. Flour thickens liquid only when heated enough to swell its starch. Stirring prevents lumps and scorching on the pan bottom, so the sauce turns smooth and binds the macaroni.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, milk, egg, parsley, pepper, nutmeg):
- Shallotfits better
- Chivefits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against butter, flour, milk, egg, parsley, pepper, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
