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

What each ingredient does

Calf's head
Provides the gelatinous meat and skin that give the soup its body and mouthfeel.
Veal stock
Forms the liquid base and carries the savory, meaty flavor of the soup.
Flour
Browned and stirred in, it thickens the stock to a smooth, body-rich consistency.
Soy sauce
Adds salty, savory depth and a deeper brown color to the finished soup.
Mushroom ketchup
Contributes concentrated umami and a dark, savory aroma to the soup.

The step that matters

Skim the soup carefully after it comes to a boil. Impurities and fat rise to the surface as the stock heats. Removing them keeps the soup clear and clean-tasting, so skimming is needed before the meat goes in.
