Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oysters: Add a briny, savoury flavour that seasons the meat from within as it cooks.
Hard boiled egg yolks: Bind the stuffing so it holds together rather than falling apart in the holes.
Leg of mutton: Forms the main body of the dish; its rich meat is slowly tenderised by gentle boiling.

The step that matters

Boiling gently in the cloth. A rolling boil can toughen meat and break the cloth-wrapped joint apart. Gentle simmering keeps the meat tender and the stuffing evenly cooked through.
