Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the stock into a smooth sauce as it cooks with the butter.
- Butter
- Cooks the vegetables and carries flavour, and the flour is cooked into it to form the base.
- Gelatine
- Adds body to the sauce so it clings to food when set or served.
- Stock
- Forms the liquid base that the sauce is built on and reduces during simmering.
The step that matters
Cook the flour until brown. Browning the flour in the butter develops nutty flavour and colour, but scorching turns it bitter. Stirring and watching closely keeps the roux evenly coloured.
Swap the onion
How well each one fits the dish's main ingredients (ham, flour, butter, carrot, celery, parsley, clove):

- Onionthe original
Fit is the average pairing score against ham, flour, butter, carrot, celery, parsley, clove. Candidates are from the same food group and used in at least 100 recipes.
