Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries the vegetables and flour and adds richness to the sauce.
- Flour
- Thickens the stock into a smooth sauce as it cooks.
- Stock
- Forms the liquid base that the flour thickens into sauce.
- Cream or milk
- Adds richness and a silky texture to the finished sauce.
The step that matters
Gradually add the stock, stirring until smooth. Adding liquid all at once to flour can form lumps. Adding it slowly while stirring lets the starch granules separate and hydrate evenly, giving a smooth sauce.
Swap the onion
How well each one fits the dish's main ingredients (butter, celery, carrot, flour, cream, pepper):
- Parsnipfits better
- Leekfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against butter, celery, carrot, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
