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 ↓
Leg of Mutton with Oysters
Ingredients
Directions
Prepare the stuffing
Parboil the fat oysters.
Mix the oysters with parsley, minced onions, sweet herbs, and the yolks of two hard boiled eggs, all chopped fine.
Stuff and cook
Cut five or six holes in the fleshy part of the leg of mutton.
Stuff the mixture into the holes.
Tie the leg of mutton in a cloth.
Boil gently for 2.5 to 3 hours, depending on the size.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fat oysters
- Provide the rich, briny flavour that fills the stuffing.
- Hard boiled egg yolks
- Add a soft, crumbly richness that binds the stuffing together.
- Leg of mutton
- Forms the main cut of meat that is flavoured by the stuffing as it cooks.
The step that matters
Boil gently for 2.5 to 3 hours. Gentle simmering cooks the thick joint through without toughening the meat, which can happen with a hard boil. Judging by the size of the leg helps set the right time.
Swap the onion
How well each one fits the dish's main ingredients (oyster, parsley, egg, mutton):
