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
How well each one fits the dish's main ingredients (turnip, carrot, celery, butter, pepper):
- Parsnipfits better
- Leekfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against turnip, carrot, celery, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
