Celery Soup

Ingredients

Directions

Prepare the celery

  1. Parboil the celery pieces in water for 5 minutes, then drain.

Make the soup

  1. In a saucepan, melt 4 ounces of butter, then add the celery, salt, pepper, and white broth. Cover and simmer for 1 hour.

  2. In another saucepan, knead 4 ounces of butter with 5 ounces of flour until combined.

  3. Stir and cook the flour mixture briefly, then dilute it with 1 quart of boiled cream and 2 quarts of veal or chicken broth.

  4. Add the cooked celery to the mixture and boil for 10 minutes.

  5. Pass the soup through a sieve and return it to the heat.

  6. Add 2 ounces of butter, 1 cup of raw cream, and 1 teaspoon of cream, stirring until combined.

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

What each ingredient does

Celery
Forms the main body and flavour of the soup as it simmers and breaks down.
Flour
Cooked with butter to form a roux that thickens the broth.
Butter
Adds richness and fat, carrying flavour and giving a smooth mouthfeel.
Cream
Adds richness and a smooth, silky texture to the finished soup.
Broth
Forms the liquid base that the roux thickens and the celery cooks in.

The step that matters

Cooking the flour mixture briefly before adding the liquid. Flour must be cooked enough to lose its raw taste and to thicken smoothly; adding liquid too early or without stirring can leave lumps and a pasty flavour.

Swap the celery

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

  1. Nutmegfits better
  2. Parsleyfits better
  3. Sagefits about as well
  4. Celerythe original

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