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

What each ingredient does

Butter
Enriches the base and carries flavour while the flour is cooked into a roux.
Flour
Thickens the soup by forming a roux with the melted butter.
Cream
Adds richness and a smooth, velvety texture to the soup.
Shin of beef
Releases gelatin and savoury flavour into the long-simmered stock.

The step that matters

Clarifying the stock after straining. Fat left on the surface makes the soup greasy and cloudy. Chilling and skimming the fat off the cooled stock gives a clearer, cleaner base before the soup is finished.

Swap the clove

How well each one fits the dish's main ingredients (butter, flour, cream, beef, veal, ham, onion):

  1. Capersfits better
  2. Garlicfits better
  3. Celeryfits better
  4. Clovethe original

Fit is the average pairing score against butter, flour, cream, beef, veal, ham, onion. Candidates are from the same food group and used in at least 100 recipes.
