Why it works: Vinegar and mustard are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
To Souse a Pig's Head
Ingredients
Directions
Prepare the meat
Cut open the pig's head and remove the brains and tongue.
Cut off the ears close to the head.
Clean all parts well and salt them with coarse sea salt.
Let them sit for 3-4 days.
Boil the salted parts until very tender, so the bones slip out easily.
Remove the bones from the head.
Press and pickle
Prepare a cloth in an earthen pot.
Layer half of the head in the pot with the skin side down, followed by one ear, the peeled and cut tongue, the other ear, and the remaining half of the head with the skin side up.
Sprinkle salt between each layer while hot.
Press down with a board and weight.
Let it sit overnight.
Remove from the pot and take off the cloth.
For long-term storage, make a pickle with the boiling liquid and vinegar or boiled bran and water.
Cool the liquid before adding the head.
Serve
To serve, slice the head (not too thin), dust with flour, and fry until heated through.
For sauce, combine vinegar, powdered sugar to taste, and prepared mustard in a saucepan.
Boil together and serve in a sauce tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig's head
- Forms the main body of the dish, with meat, skin and bones that set into a firm pressed mass.
- Coarse sea salt
- Cures the meat by drawing out moisture and seasoning it, helping preserve it.
- Vinegar
- Adds acidity to the pickling liquid and to the sauce, sharpening flavour and aiding preservation.
- Powdered sugar
- Adds sweetness to the sauce, balancing the sharpness of the vinegar and mustard.
- Prepared mustard
- Adds sharp, pungent flavour to the sauce.
The step that matters
Cool the liquid before adding the head. Pouring hot liquid over the pressed meat would partly cook and soften its surface, so it can spoil or turn mushy. Cooling it first keeps the texture firm and the pickle safer to store.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, flour, sugar, sauce):
- Mustardthe original
- Shallotfits about as well
- Horseradishfits less well
- Arrowrootfits less well
Fit is the average pairing score against vinegar, flour, sugar, sauce. Candidates are from the same food group and used in at least 100 recipes.
