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 ↓
Carrot and Sausage Stew
Ingredients
Directions
Prepare the vegetables
Scrape and slice the carrots; peel the onions and potatoes.
Cook the carrots, onions, and potatoes until very tender, then drain and reserve the water.
Cook the sausages
Boil the sausages in the reserved vegetable water for 30 minutes, then drain.
Melt the fat in a pan, add the sausages, and fry until golden brown. Keep hot.
Make the sauce and serve
Add the flour to the fat in the pan and fry for five minutes.
Gradually add the vegetable water, bring to a boil, and continue boiling for eight minutes.
Add the cooked vegetables, season to taste, slice the sausages, mix in, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the cooking liquid into a sauce when fried in fat and then simmered with the water.
- Potatoes
- Break down when cooked until very tender, adding body and starch to the stew.
- Carrots
- Soften when cooked and add sweetness and colour to the stew.
- Sausages
- Provide the main protein and savoury flavour, browned in fat for extra colour and taste.
- Onions
- Soften and turn sweet when cooked, adding savoury depth to the stew.
The step that matters
Cooking the flour in the fat. Frying the flour in the fat for five minutes cooks out its raw starchy taste. Adding the water too soon can leave lumps, so the flour should be fully mixed into the fat first.
Swap the onion
How well each one fits the dish's main ingredients (carrot, potato, flour):
- Parsnipfits better

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