Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Provide the bulk of the soup's body and mild, earthy flavor as they soften.
- Carrots
- Add natural sweetness and color while softening into the broth.
- Potatoes
- Break down slightly during long boiling, adding body and thickening the soup.
- Rice
- Releases starch as it cooks, helping to thicken the broth.
The step that matters
Add the potatoes after the first hour of boiling. Potatoes and rice would be overcooked if added too early in a long boil. Adding them after the hard root vegetables have softened helps everything finish together.
Swap the potato
How well each one fits the dish's main ingredients (turnip, carrot, parsnip, rice):
