Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turkey bones
- Release meaty flavour and body into the broth as they simmer.
- Barley
- Releases starch that thickens the broth and adds chewy texture.
- Rice
- Releases starch that adds body and softness to the broth.
- Potatoes
- Starch from the potatoes thickens the broth and softens the soup.
- Carrots
- Add natural sweetness and colour to the broth.
- Flour
- Thickens the broth when stirred in with butter near the end.
The step that matters
Boil slowly for 4 hours. A gentle simmer extracts flavour from the bones while keeping the broth clear. A hard rolling boil breaks fat into the liquid, making the soup cloudy and greasy, and can break up the vegetables and grains.
