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 ↓
To Make Irish Stew
Ingredients
Directions
Prepare
Cut the mutton into chops.
Stew
In a stew pan, layer the mutton chops with sliced potatoes, onions, pepper, salt, and hot water.
Cover the pan and let it stew slowly for 1 hour, shaking the pan occasionally to prevent sticking.
Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the meat and rich flavour that form the body of the stew.
- Potatoes
- Break down slowly during stewing, thickening the broth and adding starchy body.
- Onions
- Soften and sweeten as they stew, adding depth to the broth.
- Hot water
- Forms the cooking liquid that gently braises the mutton and vegetables.
The step that matters
Stewing slowly with the lid on. Gentle, covered simmering keeps the mutton tender and prevents the bottom from scorching or sticking. Shaking the pan helps distribute heat and loosen any stuck food.
