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
Prepare
Layer the mutton chops and sliced potatoes in a stewpan.
Add the turnips and onions on top.
Stew
Pour in 1 quart of cold water and cover the stewpan tightly.
Let it stew gently until the vegetables are soft and most of the gravy is absorbed.
Serve
Transfer to a dish, season to taste, and 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 meat and fat that flavour the stew and enrich its gravy.
- Potatoes
- Break down as they cook, thickening the gravy and giving the stew body.
- Turnips
- Soften during stewing and add a slightly sweet, earthy flavour to the gravy.
- Onions
- Soften and sweeten as they stew, adding depth to the gravy.
The step that matters
Cover the stewpan tightly and stew gently. A tight lid keeps steam in so the vegetables cook through in their own moisture. Gentle heat keeps the meat tender rather than tough and stops the potatoes from breaking apart before the gravy thickens.
Swap the turnip
How well each one fits the dish's main ingredients (mutton, potato, onion):
