Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens in the hot oil to build a savoury aromatic base for the soup.
- Oil
- Carries fat-soluble flavours and helps the vegetables cook evenly in the pan.
- Carrots
- Release natural sugars as they cook, adding gentle sweetness to the broth.
- Cabbage
- Softens into tender pieces, adding body and mild sweetness to the soup.
The step that matters
Stew gently until the vegetables are tender.. Low, gentle heat softens the vegetables' cell walls slowly while keeping them intact. Vigorous boiling at this stage can scorch the base of the pan and break the vegetables into a mush, dulling both flavour and texture.
