Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Form the bulk of the topping and release moisture that becomes the sauce as they cook.
- Flour
- Thickens the cooking liquid into a light sauce that clings to the mushrooms.
- Butter
- Fat for sautéing that carries flavour and helps the mushrooms brown.
- Beef extract
- Adds concentrated savoury, meaty flavour to the water-based sauce.
Swap the mace

- Marjoramfits better
- Macethe original
Fit is the average pairing score against mushroom, butter, flour, beef, pepper. Candidates are from the same food group and used in at least 100 recipes.
