Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Roast Pig
Ingredients
Directions
Prepare
Wash the pig thoroughly inside and out.
Mix the chopped liver, bread crumbs, onion, parsley, pepper, salt, and mashed potatoes. Combine with butter and egg to make a paste.
Stuff and roast
Stuff the mixture into the pig and sew it up.
Place the pig in a baking pan with a little water and roast over a bright fire.
Baste well with butter and rub with lard tied in a clean rag frequently.
Serve
When done, lay the pig back up in a dish and place a red apple or pickled mango in its mouth.
Make a dressing with some of the stuffing, wine, and drippings to serve with the roast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig
- Is the main roasted meat that the stuffing and drippings accompany.
- Liver
- Adds richness and savoury depth to the stuffing.
- Bread crumbs
- Absorb moisture and help bind the stuffing into a paste.
- Potatoes
- Add body and moisture to the stuffing, keeping it soft during roasting.
- Egg
- Binds the stuffing mixture together so it holds its shape.
- Butter
- Adds fat for richness and helps the skin brown as it bastes.
The step that matters
Basting and turning the pig over a bright fire. A whole pig roasts unevenly and its skin can scorch before the thick meat cooks through. Frequent basting with fat keeps the surface moist and encourages even browning, while a steady heat rather than a flare-up gives the interior time to cook.

Fit is the average pairing score against liver, bread, parsley, pepper, potato, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
