Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Form the body of the stew and soften into a sweet, tender base as they cook.
- Veal stock
- Provides the liquid and savory flavor that the stew simmers in.
- Butter and flour
- Flour thickens the liquid into a sauce, and the butter carries richness and flavor.
- Cream
- Adds richness and a smoother, milder texture when stirred in at the end.
The step that matters
Stew gently for 1 hour. A gentle simmer lets the onions soften and release their sweetness without breaking down or scorching. A vigorous boil can break the flour-thickened sauce and make it grainy or uneven.
Swap the white pepper
How well each one fits the dish's main ingredients (onion, veal, butter, flour, cream):
- Capersfits better
- Garlicfits better
- Nutmegfits better
- White pepperthe original
Fit is the average pairing score against onion, veal, butter, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
