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 ↓
Cold Roast Leg of Mutton
Ingredients
Directions
Prepare the leg
Trim the large end of the leg to make it flat.
Cut through the joint where it has been carved and remove the bone from the fillet.
Fill the cavity with veal forcemeat.
Simmer
Place the meat, bones, knuckle, and trimmings in a stew pot and cover with water or broth.
Bring to a boil, then add onions, parsley, bay leaves, carrots, and turnips.
Simmer gently for about 2 hours.
Add thickening, spice, or store-sauce to the gravy before serving.

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 and gives the meat that cooks down into the gravy.
- Veal forcemeat
- Fills the cavity, adding moisture and a tender, compact texture to the meat.
- Onions
- Add aroma and sweetness to the broth as they soften during simmering.
- Carrots
- Contribute natural sweetness and body to the cooking liquid.
- Turnips
- Add mild sweetness and earthy flavour to the gravy as they cook.
The step that matters
Simmer gently for about 2 hours. A gentle simmer keeps the liquid just below a boil, so the meat becomes tender without its proteins tightening and toughening. A rolling boil would make the meat dry and stringy and cloud the gravy.
Swap the onion
How well each one fits the dish's main ingredients (mutton, veal, parsley, carrot, turnip, sauce):
