Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Form the body of the soup and thicken it as they break down during long boiling.
- Butter
- Softens the chopped vegetables and carries flavour from the aromatics into the soup.
- Flour
- Cooked in butter until brown, it thickens the soup and adds a toasted, nutty flavour.
- Onions
- Build a sweet, savoury base as they soften in butter.
- Stock
- Adds savoury depth and body to the soup.
The step that matters
Cooking the flour in butter until brown. Flour cooked in fat until brown develops a toasted flavour and thickens less than raw flour. If it is stirred in before it browns, it can taste raw and pasty, and it may lump if not mixed in smoothly.
