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
Wash the potatoes well in cold water and scrub them clean. If they are not good, peel and cut out any bad spots.
Fill a saucepan with hot water and bring it to a boil.
Peel the onions.
Place the potatoes in a steamer and sprinkle with salt.
Open the tin of canned meat and slice the meat.
Cook
Boil the onions in the saucepan.
Cover the steamer tightly and let the potatoes steam and the onions boil for 30 minutes.
Check if the potatoes and onions are tender with a fork.
Once cooked, remove the potatoes from the steamer, peel, and slice them.
Remove the onions from the saucepan and slice them.
Assemble
In a large saucepan, layer the potatoes, onions, and meat, seasoning each layer with pepper and salt.
Pour in ½ pint of warm water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Starchy body that softens during steaming and gives the stew its bulk and texture.
- Canned meat
- Supplies the main protein and savoury flavour of the stew.
- Onions
- Soften as they cook, adding sweetness and depth to the stew.
The step that matters
Steaming the potatoes until tender. Potatoes need enough steam time to cook through evenly; undercooked centres stay firm and grainy, while overcooking makes them break apart when sliced.
Swap the onion
How well each one fits the dish's main ingredients (meat, potato, pepper):
- Capsicumfits better
- Carrotfits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against meat, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
