Why it works: Pork and onion are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 18,214 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Filled Pork
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dressing
Toast the bread crumbs in a pan.
Chop the onion into small squares.
Season the onion with pepper and coarse sea salt, then mix with the bread crumbs.
Stuff and roast
Make deep incisions in the pork with a sharp knife and fill them with the dressing.
Spread any remaining dressing over the top of the pork.
Roast the pork in the oven at 350°F (175°C) until cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pork shoulder
- Forms the main body of the dish; slow roasting breaks down its connective tissue and fat for tenderness.
- Bread crumbs
- Soak up juices and hold the dressing together, giving it a moist, soft texture.
- Onion
- Adds aroma and savory flavor to the dressing as it softens and mixes with the crumbs.
The step that matters
Roast until cooked through. A thick shoulder can brown on the outside before the centre is fully cooked, and the dressing inside can stay cool. Checking the centre with a thermometer rather than by colour helps ensure the pork is safely done.
Swap the onion
How well each one fits the dish's main ingredients (pork, bread, pepper):

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