Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mixed vegetables
- Break down when boiled to give the soup body and a naturally thick, mashed texture.
- Crushed french tapioca or sago
- Starch that swells when heated, thickening the soup into a smooth, lightly body-rich consistency.
- Ground rice or rice flour
- Starch that thickens the liquid as it heats, adding body to the soup.
- Liquor from meat or poultry
- Flavour base; reducing it concentrates the savoury taste before the soup is thickened.
The step that matters
Thicken with starch after reducing. Starch needs to be mixed with water first and then heated in the soup, so it disperses evenly. Added dry or unmixed, it clumps and leaves lumps that cannot be smoothed out.
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.
