Why it works: Thyme and pepper are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 11,585 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pig
- Forms the main body of the dish, cooked whole so the meat becomes tender and fully done.
- Stale bread
- Absorbs moisture and flavour from the stuffing, giving it a soft, tender body.
- Eggs
- Bind the stuffing together so it holds its shape when cooked.
- Flour
- Thickens the pan liquids into a smooth gravy.
- Lard
- Adds fat to the stuffing, carrying flavour and aiding browning.
The step that matters
Cook until thoroughly done. A whole pig is thick and dense, so the centre can stay undercooked while the outside browns. Cooking it fully, and checking the thickest parts, makes it safe to eat.
Swap the onion
How well each one fits the dish's main ingredients (bread, egg, butter, sugar, thyme, pepper, flour):
- Shallotfits better
- Leekfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against bread, egg, butter, sugar, thyme, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
