Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries the cooking of the onion and carrot and adds richness to the finished sauce.
- Flour
- Thickens the liquid as its starch swells with heat, giving the sauce body.
- Chicken or veal stock
- Forms the main liquid that the flour thickens into a sauce.
- Cream
- Adds fat and smoothness, giving the sauce a rich, silky texture.
- Onion
- Softens and browns in butter, adding savory sweetness and aroma to the base.
The step that matters
Gradually add the stock and cream, stirring continuously. Adding liquid slowly while stirring lets the flour starch disperse evenly, which prevents lumps and produces a smooth, even sauce.

How well each one fits the dish's main ingredients (butter, onion, flour, pepper, chicken, cream):
- Potatofits better
- Leekfits better
- Chivefits better
- Carrotthe original
Fit is the average pairing score against butter, onion, flour, pepper, chicken, cream. Candidates are from the same food group and used in at least 100 recipes.
