Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Liquor from meat or poultry
Provides the main savoury body and flavour of the soup.
Mixed vegetables
Add sweetness, aroma and body as they break down during boiling and sieving.
Tapioca or sago
Thickens the liquid as its starch swells when heated, giving a smooth texture.
Ground rice or rice flour
Adds starch that thickens the soup and gives it a smooth, light body.
Corn flour or potato flour
Thickens the soup through starch gelatinising when heated in the liquid.
Cooked grain or cold macaroni
Adds body and substance, with its own starch helping the soup thicken.

The step that matters

Thickening the soup. Starches such as flour, tapioca or rice only thicken fully when the liquid is hot enough for the granules to swell and gelatinise. Stir while adding them to prevent lumps, then cook long enough so the raw starch taste disappears and the texture stops being thin or grainy.

Swap the onion

How well each one fits the dish's main ingredients (meat, celery, leek, turnip, carrot, parsnip, parsley):

  1. Beetrootfits better
  2. Shallotfits better
