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

What each ingredient does

Haricot beans
Hold their shape while adding body and starch that thickens the soup.
Savoy cabbage
Adds bulk and a tender, slightly sweet vegetable texture as it cooks down.
Rice
Releases starch as it cooks, thickening the broth and giving the soup body.
Smoked sausages
Contribute smoky, savoury flavour and fat that enriches the broth.
Raw ham
Flavours the broth with savoury, salty meat richness as it simmers.
Chopped bacon
Renders fat and smoky savouriness into the broth as it cooks.

The step that matters

Simmer until the rice is cooked. Rice keeps absorbing liquid and releasing starch as it sits, so it can turn mushy or over-thicken the soup if simmered too long. Gentle heat keeps the soup at a steady simmer rather than a hard boil, which would break up the vegetables and beans.

Swap the cabbage
