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 stew and release moisture that flavors the sauce as they cook.
Eggs
Beaten in at the end, they thicken the mixture gently as they set without boiling.
Butter
Adds richness and fat, carrying flavor and helping the mushrooms brown and soften.
Onion
Adds savory sweetness and aroma as it softens into the base of the stew.
Mushroom ketchup
Concentrates deep, savory umami flavor into the stew.

The step that matters

Stir the eggs in without boiling. Egg proteins set and curdle when overheated, so the mixture must stay below a boil to stay smooth and thickened rather than grainy.

Swap the nutmeg

How well each one fits the dish's main ingredients (mushroom, onion, butter, ketchup, vinegar, pepper, egg):

  1. Parsleyfits better
  2. Garlicfits better
  3. Thymefits better
  4. Nutmegthe original

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