Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turkey bones
- Give the stock its deep, roasted meaty flavor as they simmer for hours.
- Browned flour
- Thickens the soup and adds a toasted, nutty color and flavor.
- Pickled pork
- Adds salty, savory depth to the broth as it cooks.
- Carrot
- Adds sweetness and body to the stock as it breaks down while simmering.
- Onion
- Adds savory sweetness and aroma to the base of the soup.
- Cooking wine
- Adds acidity and a rounded aroma to finish the soup.
The step that matters
Skimming during the long boil. Skimming removes foam and impurities that rise to the surface, keeping the broth clear and clean-tasting over the four-hour simmer.
