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 ↓
Spare Ribs
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).
Prepare the stuffing by mixing sage and chopped onion.
Stuff the spare rib with the sage and onion mixture.
Roast and serve
Place the stuffed spare rib in a roasting pan over sliced potatoes.
Roast in the oven until the meat is cooked through and tender.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spare rib of pork
- Forms the main body of the dish and provides the meat that becomes tender during roasting.
- Sage
- Adds a savory, aromatic flavor to the stuffing and the meat.
- Onion
- Adds sweetness and moisture to the stuffing as it softens in the heat.
- Potatoes
- Sit beneath the rib in the pan, absorbing drippings and browning at the edges as they roast.
The step that matters
Roast until the meat is cooked through and tender. Pork needs to reach a safe internal temperature, and a large cut like a rib stays tough if removed too early. Cooking it fully lets connective tissue break down, so the meat becomes tender rather than chewy.
Swap the sage
How well each one fits the dish's main ingredients (pork, onion, potato):
- Garlicfits better
- Thymefits better
- Celeryfits better
- Sagethe original
Fit is the average pairing score against pork, onion, potato. Candidates are from the same food group and used in at least 100 recipes.
