Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Browns with the butter to form a roux that thickens the stew's liquid.
- Veal
- Becomes tender during slow simmering, forming the main body of the stew.
- Butter
- Carries the flour's browning and adds rich flavour to the base.
- Onion
- Softens and adds savoury sweetness to the stew's base.
The step that matters
Cook slowly for 2 hours until the veal is tender. A gentle simmer lets collagen in the veal break down slowly into gelatin, making it tender and juicy. Boiling hard toughens the meat fibres and can leave the stew cloudy.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, veal, pepper):
- Shallotfits better

- Capsicumfits better
- Onionthe original
Fit is the average pairing score against butter, flour, veal, pepper. Candidates are from the same food group and used in at least 100 recipes.
