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 flavor of the sauce as they soften in the gravy.
Thickening
Thickens the sauce to a smooth, coating consistency as it simmers.
Mushroom ketchup
Adds concentrated savory, umami depth to the finished sauce.

The step that matters

Add thickening to the sauce. Starch must be fully hydrated and brought to a simmer to thicken properly. Adding it to a sauce that is too cool or stirring poorly can leave lumps or a thin, uneven texture.

Swap the mace

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

  1. Marjoramfits better
  2. Thymefits better
  3. Turmericfits better
  4. Macethe original

Fit is the average pairing score against mushroom, pepper, flour, ketchup. Candidates are from the same food group and used in at least 100 recipes.
