Why it works: Parsley and butter are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 28,563 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Forms the main body of the dish, becoming tender and juicy during long, gentle simmering.
- Salt
- Seasons the cooking water so the meat is flavoured from the outside in.
The step that matters
Boil slowly, skimming the scum. Gentle simmering keeps the meat tender, while a vigorous boil toughens muscle fibres and churns the scum back into the liquid, clouding it and spoiling the texture.
Swap the parsley
How well each one fits the dish's main ingredients (mutton, butter):
- Pepperfits about as well
- Parsleythe original
- Capersfits about as well
- Thymefits less well
Fit is the average pairing score against mutton, butter. Candidates are from the same food group and used in at least 100 recipes.
