Why it works: Parsley and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Boiled Leg of Mutton
Ingredients
Directions
Prepare
Cut off the shank bone and trim the knuckle of the leg of mutton.
Wash and wipe it clean.
Boil
Place the leg of mutton in a pot of boiling water and add the peeled onion.
Boil until no blood follows an incision with a fork, about 2 hours and 15 minutes after the water begins to simmer.
Skim the water well and add a little salt.
Serve
Serve garnished with parsley or celery leaves, alongside boiled carrots and mashed turnips, with caper sauce in a tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Is the main meat, which becomes tender and juicy as it simmers slowly in water.
- Onion
- Adds a mild aromatic flavour to the cooking water that subtly seasons the meat.
- Caper sauce
- Adds a sharp, acidic contrast that cuts through the richness of the boiled mutton.
The step that matters
Boil until no blood follows an incision. Boiling must continue until the meat is fully cooked through and no blood runs from the thickest part. Stopping early leaves the meat undercooked, while the gentle simmer keeps the fibres tender rather than tough.
Swap the onion
How well each one fits the dish's main ingredients (mutton, meat, parsley, carrot, turnip, sauce):

Fit is the average pairing score against mutton, meat, parsley, carrot, turnip, sauce. Candidates are from the same food group and used in at least 100 recipes.
