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, with Salt Beef
Ingredients
Directions
Prepare
Wash the salt beef in cold water, separate it from the bone, and cut it into small pieces, about 2 ounces each.
Rinse the cut salt beef again in cold water.
Peel and clean the potatoes, then peel and slice the onions.
Cook
In a large pot, combine the meat, potatoes, and onions.
Add pepper and enough cold water to cover everything.
Cover the pot and cook gently over low heat, skimming off any fat that rises to the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt beef
- Provides the main meat flavour and body of the stew.
- Potatoes
- Break down as they cook, thickening the broth and adding starchy body.
- Onions
- Add sweetness and aromatic depth to the cooking liquid.
The step that matters
Skimming off the fat. Fat that rises during gentle simmering can make the stew greasy and cloudy. Removing it as it forms keeps the broth clean-tasting.
