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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb chops
- Provide the main meat, which becomes tender and flavorful as it simmers in the stew.
- White potatoes
- Add starch that softens during simmering and thickens the stew slightly.
- Onions
- Contribute sweetness and aroma as they cook down into the broth.
- Flour
- Dusts the mixture so the cooking liquid thickens into a smoother stew.
The step that matters
Set the kettle over low heat and let it simmer until fully cooked. Gentle, low heat lets the collagen in the lamb break down slowly into tender meat without toughening the proteins. A rapid boil can make the meat tough and can break up the potatoes.
Swap the onion
How well each one fits the dish's main ingredients (lamb, potato, pepper, flour):
- Okrafits better
- Spinachfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against lamb, potato, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
