Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour while it melts with the flour.
- Flour
- Thickens the stock into a smooth sauce when cooked with the butter.
- Chicken stock
- Forms the liquid base that gives the sauce its savoury body.
- Milk
- Adds creaminess and mellows the sauce's flavour.
- Mushrooms
- Contribute earthy flavour and texture to the finished sauce.
The step that matters
Adding the flour to the butter. Stir the flour into the melted butter until smooth, then add the stock gradually. Cooking the flour in fat helps prevent lumps and gives the sauce a thickened, even texture.
Swap the mace
How well each one fits the dish's main ingredients (butter, flour, chicken, onion, carrot, parsley, milk):
- Thymefits better
- Celeryfits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against butter, flour, chicken, onion, carrot, parsley, milk. Candidates are from the same food group and used in at least 100 recipes.
