Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Softens and turns sweet and aromatic as it cooks in the broth.
- Carrots
- Adds natural sweetness and body to the soup.
- Oatmeal or flour
- Thickens the broth as its starch swells in the hot liquid.
- Bread
- Soaks up liquid and adds body, helping thicken the soup.
- Thyme
- Adds a savory, herbal aroma to the broth.
- Parsley
- Adds fresh, green flavor to the finished soup.
The step that matters
Stirring in the oatmeal or flour. Starch clumps when it hits hot liquid all at once. Stirring it in steadily and keeping the liquid moving lets each grain disperse and swell evenly, so the soup thickens smoothly instead of lumping.
