Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as it cooks with the butter.
- Butter
- Carries flavour and enriches the sauce while the flour cooks in it.
- Red wine
- Adds acidity and depth of flavour to the sauce.
- Onions
- Become soft and sweet as they stew in the sauce.
The step that matters
Mix flour and butter until brown. Cooking the flour in the butter builds a roux. If it is pulled off the heat too early it stays pasty and tastes raw, and if it burns it turns bitter. Stirring keeps it even so the sauce thickens smoothly.
Swap the onion
How well each one fits the dish's main ingredients (flour, butter, red wine, parsley, chive, clove, thyme):
- Shallotfits better

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