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

What each ingredient does

Brown sauce: Provides the rich, savory body that coats the head and tongue.
Mushrooms: Add earthy flavor and a meaty texture to the sauce.
Lemon juice: Adds acidity that brightens the rich, heavy brown sauce.
