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 ↓

Sauce and butter barely smell alike, yet cooks put them together in 15,338 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the starchy base that gives the dish its body.
- Hard-boiled eggs
- Supply firm, mild protein texture and rich flavour to the dish.
- White sauce or cream
- Adds moisture and a creamy, smooth coating to the pasta.
- Butter
- Adds fat for richness and a silky mouthfeel in the sauce.
The step that matters
Cooking the macaroni until nearly tender. Pasta keeps softening in its own heat and in the sauce, so stopping just short of tender keeps it from turning mushy once combined and served.
Swap the parsley
How well each one fits the dish's main ingredients (egg, pepper, sauce, butter):
- Parsleythe original
- Tarragonfits about as well
- Capersfits about as well
- Nutmegfits less well
Fit is the average pairing score against egg, pepper, sauce, butter. Candidates are from the same food group and used in at least 100 recipes.
