What each ingredient does
- Pig's head
- Skin and bones release gelatin during boiling, which helps the brawn hold together when cooled.
- Saltpetre
- Cures the meat, helping preserve it and giving it a pink colour.
- Coarse sea salt
- Draws out moisture and seasons the meat, aiding preservation.
- Vinegar
- Adds acidity that sharpens the flavour and helps keep the finished brawn fresh.
The step that matters
Boil the head until the bones can be easily removed. Boiling too little leaves the meat tough and the bones hard to remove. Boiling too long breaks the meat down too far. Skin and bone collagen turns into gelatin during cooking, which is what sets the brawn when it cools.
