Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mixed vegetables
- Provide body, sweetness and flavour once boiled down and sieved into the soup.
- Crushed french tapioca or sago
- Thickens the soup as its starch swells during cooking.
- Ground rice or rice flour
- Thickens the soup as its starch swells when cooked in a paste.
The step that matters
Thicken with tapioca, sago or rice flour. Starches only thicken fully when cooked long enough to swell and gelatinise. Undercooked starch leaves the soup thin and gives a raw, chalky taste, so follow the stated cooking time for the chosen thickener.
Swap the onion
How well each one fits the dish's main ingredients (meat, celery, leek, turnip, carrot, parsnip, parsley):
- Beetrootfits better
- Shallotfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against meat, celery, leek, turnip, carrot, parsnip, parsley. Candidates are from the same food group and used in at least 100 recipes.
