Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox foot
- Releases collagen and flavour into the broth during long simmering, giving body to the soup.
- Pea flour
- Thickens the broth as it cooks, giving the soup a fuller, smoother body.
- Leeks
- Add a mild onion-like sweetness and aroma to the broth.
- Potatoes
- Release starch into the broth, adding body and making the soup heartier.
The step that matters
Adding the pea flour mixture. Flour mixed into hot liquid clumps unless it is first blended smoothly with cold water, so stirring it into a small amount of water before adding it keeps the soup smooth and evenly thickened.
Swap the tomato
How well each one fits the dish's main ingredients (leek, turnip, potato, saffron, carrot, celery, parsley):
- Parsnipfits better
