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

What each ingredient does

Pig's head
Provides the meat, skin and gelatinous connective tissue that set the brawn.
Saltpetre
Gives the cured meat its pink colour and characteristic cured flavour.
Sugar
Balances the saltiness of the cure and softens the flavour of the meat.
Coarse sea salt
Draws out moisture and seasons the meat during curing.
Vinegar
Adds acidity to the pickle, sharpening the flavour of the ears and feet.

The step that matters

Boil gently for 4 hours. Gentle simmering slowly converts collagen in the bones and skin into gelatin, which sets the brawn. A hard boil can toughen the meat and cloud the liquid.

Swap the mace
