Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that fries the mushrooms and cooks the flour into a roux, carrying flavour and richness.
- Flour
- Thickens the sauce and, cooked until dark brown, adds colour and a toasted flavour.
- Mushrooms
- Provide the main earthy flavour and body of the sauce.
- Stock
- Forms the liquid base of the sauce, adding savoury depth.
The step that matters
Cooking the flour until dark brown. Flour must be cooked long enough to lose its raw taste and develop colour and nutty flavour, but stopped before it burns and turns bitter. Stirring constantly prevents scorching and lumps when the stock is added.
Swap the clove
How well each one fits the dish's main ingredients (turnip, carrot, onion, butter, flour, mushroom):
- Parsleyfits better
- Thymefits better
- Capersfits better
- Clovethe original
Fit is the average pairing score against turnip, carrot, onion, butter, flour, mushroom. Candidates are from the same food group and used in at least 100 recipes.
