Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Provide the main body and earthy flavour of the sauce.
- Butter
- Carries flavour and helps the onion and mushrooms brown in the pan.
- Onion
- Adds sweetness and savoury depth as it softens and browns.
- Brown stock or hot water
- Adds liquid so the sauce can simmer and become a sauce.
- Beef extract
- Adds concentrated savoury, meaty flavour to the liquid.
The step that matters
Cook the mushrooms, onion, and garlic until golden brown. Browning builds deep flavour through the Maillard reaction. Pale, steamed vegetables give a flat, bland sauce, so the pan should be hot enough for them to colour rather than release liquid.
Swap the clove
How well each one fits the dish's main ingredients (mushroom, onion, garlic, butter, beef):
- Thymefits better
- Parsleyfits better
- Cuminfits better
- Clovethe original
Fit is the average pairing score against mushroom, onion, garlic, butter, beef. Candidates are from the same food group and used in at least 100 recipes.
