Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,118 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
The recipe
Ingredients
Contains: egg, tree nuts (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the head
Clean and singe the ears of the pig's head, then cut out the nose bone and brains without cutting the skin.
Keep the film of the eyes whole and soak the head in vinegar and sweet herbs for 8-10 days, or in salt for 3-4 days.
Bone the head and lay pieces of meat where it is thinnest.
Stuff and tie
Wash the head with yolk of egg and sprinkle with parsley, mace, pepper, garlic, and coarse sea salt.
Cover with high-seasoned bacon farce and lay large fillets of seasoned bacon across it.
Fill the head with a mixture of bacon, pistachios, truffles, orange chips, confected melon or citron, and almonds or cocoa-nut.
Sew the head tightly to maintain its shape and wrap it in a clean cloth.
Braise
Place it in a kettle with 3 bottles of red wine, cider, or ale and braising ingredients.
Bring to a boil or quick simmer, covering with buttered paper.

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, and its meat and skin hold the stuffing together while cooking.
- Vinegar
- Acidity in the soaking liquid firms the meat and adds a sharp tang.
- Yolk of egg
- Binds the seasonings to the surface and helps the coating set during cooking.
- Bacon
- Adds fat and savory flavor to the farce and the wrapping fillets, keeping the stuffing moist.
- Truffles
- Add a strong, earthy aroma that perfumes the stuffing.
- Red wine, cider, or ale
- Liquid for braising that tenderizes the meat and adds flavor to the cooking broth.
The step that matters
Sew the head tightly before braising. A loose seal lets the stuffing escape or dry out, and a firm wrap in a cloth helps the head keep its shape as collagen softens during long, gentle cooking.
Flavor stand-ins for the pistachio

- Pistachiothe original
Fit is the average pairing score against vinegar, egg, parsley, mace, pepper, garlic, truffle. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
