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

What each ingredient does

Haricots
Dried beans that break down during long boiling, giving the soup its body and thickness.
Sago or tapioca
Starch that thickens the soup as it cooks, giving it a smoother, heavier texture.
Butter
Adds richness and a rounded flavour to the finished soup.
Onions
Build savoury sweetness and aroma as they simmer with the beans.

The step that matters

Boil the haricots for several hours. Dried beans need prolonged boiling to soften fully; if they stay firm, the sieved soup will be grainy and uneven.

Swap the onion
