Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tail
- Releases gelatin and meat flavor into the stock during long, gentle stewing.
- Onion
- Adds savory sweetness and aroma as it softens and flavors the stock.
- Carrot
- Contributes natural sweetness and body to the stock during simmering.
- Turnip
- Adds earthy flavor and body to the stock during simmering.
The step that matters
Skim the surface after the stock comes to a boil. Proteins and fat rise to the surface as the liquid heats. Skimming them removes cloudiness and greasiness, leaving a clearer, cleaner-tasting soup.
