Why it works: Onion and potato 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
- Provides the main meat flavour and, as it simmers, becomes tender and rich.
- Beefsteak
- Adds further meat flavour and body to the broth as it simmers.
- Potatoes
- Soften during simmering, giving the stew body and absorbing its flavour.
- Onion
- Adds savoury, sweet aroma that deepens the flavour of the broth.
The step that matters
Simmer until tender. Gentle simmering, rather than a hard boil, lets the connective tissue in the meat break down slowly, so it turns tender without tightening and toughening. Keeping the heat low also prevents the potatoes from breaking apart.
Swap the onion
How well each one fits the dish's main ingredients (lamb, potato, pepper):
- Spinachfits better
- Asparagusfits better

- Onionthe original
Fit is the average pairing score against lamb, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
