Why it works: Potato and onion 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
Assemble
Layer the mutton chops, sliced potatoes, turnips, and onions in a stew pan.
Pour in nearly 1 quart of cold water.
Cook
Cover the stew pan tightly and simmer gently for about two hours until the vegetables are soft and most of the gravy is absorbed.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton chops
- Provide the main meat and rich flavor that the stew is built around.
- Potatoes
- Add starch that softens during simmering and thickens the gravy slightly.
- Turnips
- Contribute a mildly sweet, earthy flavor and soften during long simmering.
- Onions
- Add sweetness and aroma that blend into the cooking liquid.
The step that matters
Keeping the lid tight while simmering. A tightly covered pot holds in steam so the liquid cannot evaporate too fast. Gentle simmering breaks down the meat's connective tissue slowly, leaving it tender rather than tough.
Swap the turnip
How well each one fits the dish's main ingredients (mutton, potato, onion):
- Chivefits better
- Leekfits better
- Carrotfits better
- Turnipthe original
Fit is the average pairing score against mutton, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
