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

What each ingredient does

Lamb leg
Provides the main protein, which becomes tender and firm as it cooks through.
Oyster sauce
Adds savoury, salty depth to the finished meat at the table.

The step that matters

Boil the leg gently until cooked through. A gentle simmer cooks the meat evenly and keeps it tender, while a hard boil can toughen the outer layers before the centre is done.

Swap the parsley

How well each one fits the dish's main ingredients (lamb, oyster, sauce, butter):

  1. Capersfits better
