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 ↓
Pork Rib Roast
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.
Prepare
Preheat the oven to 350°F (175°C).
Mix dry bread with chopped onion or sage and season well to make a dressing.
Stuff the dressing inside the ribs, roll them up, and tie securely.
Season the outside of the ribs.
Roast
Roast the ribs in the oven for two hours.
Bake potatoes in the same pan if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Side of spare ribs
- Forms the main cut that is rolled around the stuffing and roasted.
- Dry bread
- Soaks up juices and forms the body of the dressing inside the roll.
- Onion or sage
- Adds aroma and savory flavor to the dressing.
- Potatoes
- Absorb drippings from the pan and become tender and flavorful as they roast.
The step that matters
Tying the ribs securely. If the roll is loose, the stuffing can spill out and the meat cooks unevenly. Firm, even rolling and tying keeps the dressing enclosed and the roast a compact shape for even heat penetration.
