Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Leg of Fresh Pork Roasted
Ingredients
Directions
Prepare the pork
Score the leg of pork in crossed lines.
Loosen the bone with a knife and remove it.
Fill the cavity with a rich stuffing made from stale bread, seasoned with butter, coarse sea salt, black pepper, and onion.
Sew the opening to prevent the stuffing from coming out.
Roast and serve
Place the pork on a spit.
Baste the pork with fresh butter.
Cook for 3 to 4 hours, depending on the size.
Serve with hot apple sauce and fried fresh potatoes cut into quarters.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork leg
- Provides the main meat, which becomes tender and juicy during long, slow cooking.
- Stale bread
- Forms the body of the stuffing and soaks up butter and juices as it cooks.
- Butter
- Adds richness and moisture, and helps the surface brown when basted.
- Onion
- Adds savory aroma and depth of flavour to the stuffing.
The step that matters
Cook for 3 to 4 hours, depending on the size. A stuffed joint needs enough time for the thickest part and the centre of the stuffing to reach a safe internal temperature. Judging by size rather than checking the internal temperature risks undercooked meat or dry outer layers.
Swap the apple
How well each one fits the dish's main ingredients (pork, bread, butter, pepper, onion, sauce, potato):
- Avocadofits better
- Mangofits better
- Coconutfits about as well
- Applethe original
Fit is the average pairing score against pork, bread, butter, pepper, onion, sauce, potato. Candidates are from the same food group and used in at least 100 recipes.
