Why it works: Pepper and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 27,814 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
To Collar Pig’s Head
Ingredients
Directions
Prepare
Scour the pig's head and ears thoroughly.
Remove the hair, snout, eyes, and brains.
Soak the head in water overnight.
Cure
Drain the head and rub it with saltpetre and common salt.
Cover the head with water and let it sit for two days.
Cook and press
Wash the head well and boil until the bones come out.
Remove the bones and chop the meat into 1-inch pieces.
Season the meat with pepper and salt.
Press the chopped meat into a pan lined with skin, then cover with another piece of skin.
Set and finish
Let it cool to set.
Boil 2 ounces of salt, 1 pint of vinegar, and a quart of the cooking liquid, then pour over the head.

What each ingredient does
- Pig's head
- Supplies the meat, and the skin and bones release gelatin that helps the dish set as it cools.
- Saltpetre
- Cures the meat, helping preserve it and giving it a firmer, pinkish cured colour.
- Common salt
- Draws out moisture and seasons the meat during curing and finishing.
- Vinegar
- Adds acidity that sharpens the flavour of the rich meat and cooking liquid.
The step that matters
Curing with saltpetre and salt. Rubbing the head thoroughly with saltpetre and salt, then leaving it to sit in the brine for two days, lets the cure penetrate and preserve the meat. Too little curing leaves the meat poorly preserved, while uneven rubbing gives patchy colour and seasoning.
