Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mushrooms
Form the main body of the dish and release moisture that becomes part of the sauce as they cook.
Butter
Adds fat and richness, and helps the mushrooms brown as they sauté.
Flour
Thickens the cooking liquid into a light sauce that clings to the mushrooms.
Fluid beef
Adds savoury, meaty flavour to the mushroom sauce.

The step that matters

Sautéing the mushrooms with flour. Mushrooms hold a lot of water. If they are crowded or cooked too gently, they steam instead of browning, and the flour may clump rather than thicken the liquid smoothly.

Swap the mace

How well each one fits the dish's main ingredients (mushroom, butter, flour, beef, pepper):

  1. Thymefits better
  2. Parsleyfits better
  3. Marjoramfits better
  4. 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.
