Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens and sweetens as it braises, forming the savoury base of the soup.
- Sweet potato
- Breaks down during simmering to add body, sweetness and creaminess to the purée.
- Green peas
- Provide fresh sweet flavour and colour, and add body when pureed.
- Tomatoes
- Add acidity and moisture that balance the sweetness of the peas and potato.
- Garlic
- Adds pungent aroma that mellows and sweetens when gently cooked in the pot.
The step that matters
Puree in batches until smooth. Blending hot liquid fills the blender and can build pressure, so cook must leave a vent open and fill only partway. Thorough blending breaks down the cooked sweet potato and peas for a silky texture.

Fit is the average pairing score against garlic, ginger, pepper, coriander, cumin, cardamom, clove. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
