Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat for frying the vegetables, adding richness and helping them brown.
- White wine
- Adds acidity and aroma that brighten the broth.
- Fish
- Provides the main flavour and body of the soup as it simmers.
- Onions
- Build sweetness and savoury depth when browned in butter.
The step that matters
Frying the vegetables until browned. Browning caramelises the natural sugars in the carrots, onions and celery, creating deeper savoury flavour in the finished broth. Pale vegetables give a flatter, less complex soup.
Swap the onion
How well each one fits the dish's main ingredients (butter, carrot, celery, shallot, clove, thyme, parsley):
