Why it works: Clove and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 7,874 recipes mention both. Both carry estragole, which smells anise, licorice. The science ↓
Boiled Pig's Head , with Onion-sauce
Ingredients
Directions
Prepare
Wash the pig's head thoroughly in plenty of tepid water.
Remove the brains and discard them.
Cut out the small veins and any splinters of bone.
Wash the head with plenty of coarse sea salt to cleanse it from blood.
Soak the head in pickle for three days.
Cook
After salting, place the head in a saucepan, cover it with cold water, and bring it to a boil.
Once boiling, reduce the heat and let it simmer gently for 1.5 to 2 hours, depending on the size and age of the pig.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig's head
- Supplies the meat and collagen that give the cooked head its tender texture and enrich the liquid.
- Onions
- Add sweetness and savoury depth to the cooking liquid.
- Black peppercorns
- Add sharp, warm aroma to the cooking liquid.
- Mace
- Adds a delicate, warm aroma to the cooking liquid.
- Cloves
- Add strong, warm aroma to the cooking liquid.
- Allspice
- Adds warm, sweet-spiced aroma to the cooking liquid.
The step that matters
Simmer gently after boiling. Once the water reaches a boil, lowering the heat to a gentle simmer keeps the meat tender. A hard, rolling boil toughens muscle fibres and can break the head apart while it cooks.

Fit is the average pairing score against clove, allspice, onion. 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).
