Why it works: Parsley and onion are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Boiled Leg of Mutton with Oyster Stuffing
Ingredients
Directions
Prepare the stuffing
Remove the gills and inedible parts from the oysters and parboil them.
Chop the oysters with boiled parsley, onion, and sweet herbs.
Add the yolks of 2-3 hard-boiled eggs to the mixture.
Stuff and cook the leg
Make 5–6 incisions in the leg of mutton and fill them with the stuffing.
Tie the leg in a cloth and boil in plenty of water for 2.5 hours, depending on size.
Serve
Remove the cloth, place the leg on a dish, and serve immediately.

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 carries the stuffing while it cooks.
- Oysters
- Add a briny, savoury flavour to the stuffing and become tender when parboiled.
- Hard-boiled egg yolks
- Bind the chopped mixture together and add richness to the stuffing.
The step that matters
Tie the leg in a cloth and boil it. Boiling in plenty of water cooks the thick joint gradually and evenly. Too little water or too brief a boil can leave the centre undercooked, while the stuffing needs the meat fully cooked to be safe.
Swap the onion
How well each one fits the dish's main ingredients (mutton, oyster, parsley, egg):
- Shallotfits better
- Cucumberfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against mutton, oyster, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
