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 ↓
Irish Stew
Ingredients
Directions
Prepare
Cut the mutton into serving pieces and trim off excess fat.
Cover the onions with boiling water for a few minutes, then slice them into rings.
Boil the potatoes for 15 minutes, then drain and set aside.
Cook
In a pot, layer the mutton, potatoes, and onions, adding water to cover.
Simmer until the meat is tender and the flavors meld, about 1.5 to 2 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Neck of mutton
- Provides the main meat, whose connective tissue softens into tender meat during long simmering.
- Onions
- Add sweetness and aroma as they soften and release their flavor into the broth.
- Potatoes
- Thicken the stew slightly as their starch breaks down, and absorb flavor from the broth.
The step that matters
Simmer until the meat is tender. Mutton neck is tough and needs a long, gentle simmer so its collagen breaks down into gelatin. Boiling hard can toughen the meat and break up the potatoes.
Swap the potato
How well each one fits the dish's main ingredients (mutton, onion):
- Leekfits about as well
- Potatothe original
- Turnipfits less well
- Chivefits less well
Fit is the average pairing score against mutton, onion. Candidates are from the same food group and used in at least 100 recipes.
