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

What each ingredient does

Bones
Long simmering draws gelatin and flavour from the bones into the water, giving the soup body.
Broken rice
Its starch thickens the soup as it cooks.
Carrots
Add sweetness and colour to the broth as they soften.
Turnips
Add mild sweetness and soft texture as they cook through.
Onion
Adds savoury aroma and depth to the broth.

The step that matters

Boiling the bones for three to four hours. Bones release gelatin and flavour slowly over long cooking. Stopping early leaves a thin, weak broth, so the bones need the full simmer before the vegetables go in.
