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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton chops
- Provide the meat, whose fat and juices flavour the stew as it simmers.
- Potatoes
- Soften during slow simmering and thicken the stew as their starch releases into the liquid.
- Onions
- Break down during simmering, adding sweetness and body to the gravy.
The step that matters
Simmer gently until the potatoes are soft and most of the gravy is absorbed.. A gentle simmer under a tight lid cooks the meat and potatoes evenly without toughening the meat or breaking the potatoes apart. Stopping too early leaves the potatoes firm, while over-reducing dries the stew out.
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.
