Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the meaty flavor and body that the stock carries into the soup.
- Bones
- Release gelatin and savory flavor into the water during long simmering, adding body to the stock.
- Onions
- Add sweetness and aroma as they cook slowly into the stock.
- Carrots
- Contribute natural sweetness and aroma to the stock.
- Turnips
- Add mild sweetness and earthy flavor to the stock.
- Tomato ketchup
- Adds sweetness and acidity to the finished soup.
The step that matters
Skim the surface. Skimming the foam that rises during the first boil removes impurities that would otherwise cloud the stock and taint its flavor.
