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 the meat and onions
Cut the meat into bite-sized pieces.
Peel the onions, slicing them into rings.
Combine the meat, onions, salt, pepper, and cold water in a saucepan.
Bring to a boil, skimming off any scum.
Reduce to a simmer for 1 hour, stirring occasionally.
Prepare and cook the potatoes
Scrub and wash the potatoes. Peel them thinly. Remove any eyes. Wash again.
In another saucepan, add cold water and 1 teaspoon of salt. Add the potatoes. Boil gently for 5 minutes.
Strain the potatoes. Steam and dry the potatoes.
Place the potatoes on top of the meat in the stew. Let it simmer for an additional 30 minutes, shaking the pan occasionally to prevent burning.
Serve
When done, arrange the potatoes around a hot dish, with the meat, onions, and gravy in the center. Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef or mutton
- Long simmering softens the meat and builds rich, savory flavor in the stew.
- Potatoes
- Starch thickens the cooking liquid and the potatoes soften into a hearty, filling base.
- Onions
- Break down during simmering, adding sweetness and body to the gravy.
The step that matters
Skimming the scum after boiling. Scum rising at the start is coagulated protein and impurities. Removing it keeps the gravy clear and free of off flavors.
