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

What each ingredient does

Prawns
Their shells and flesh give the soup its main flavor and body when pounded and strained.
Rice
Boiled and pounded into the puree, it thickens the soup and gives it a smooth body.
Butter
Fat carries aroma from the frying vegetables and rounds out the soup's richness.
Carrots
Frying them builds sweetness and savory depth in the base.
Sauternes wine
Its acidity and sweetness add aromatic depth as it reduces during boiling.
Veal consommé
Provides a savory, gelatin-rich liquid that carries the flavor of the soup.

The step that matters

Keep the soup cool, then heat without boiling. Boiling a puree made with egg-free thickening can cause it to separate or turn grainy, and it can dull the delicate flavor of the shellfish and butter. Gentle heat keeps the texture smooth.

Swap the celery

How well each one fits the dish's main ingredients (carrot, parsley, butter, thyme, pepper, wine, rice):

  1. Marjoramfits better
  2. Rosemaryfits about as well
  3. Tarragonfits about as well
  4. Celerythe original

Fit is the average pairing score against carrot, parsley, butter, thyme, pepper, wine, rice. Candidates are from the same food group and used in at least 100 recipes.
