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
- Veal
- Provides the main meat, and browning it first builds savoury flavour in the stew.
- Potatoes
- Their starch softens during simmering and adds body to the stew.
- Onion
- Adds aroma and gentle sweetness as it softens in the stock.
- Stock
- Supplies the liquid that cooks the meat and forms the gravy.
- Flour
- Its starch thickens the cooking liquid into a smooth gravy.
- Vinegar
- Adds a sharp acidity that balances the richness of the meat and gravy.
The step that matters
Thicken the gravy with flour, then let it boil. Flour must be fully mixed in and brought to a boil so its starch swells and thickens the gravy. Stopping early leaves lumps and a raw, floury taste.
