A Cheap Soup

Ingredients

Directions

Prepare the soup

  1. Wash the barley in cold water.

  2. In a soup pot, combine the barley and beef with enough cold water to cover.

  3. Bring to a boil, skim the surface, and add the onions.

  4. Reduce heat and simmer gently for 2 hours.

  5. Skim off any fat, then add the celery and turnip.

  6. Season with salt and boil for another 1.5 hours.

Thicken and serve

  1. Remove the meat and keep warm, then skim the broth.

  2. In a basin, mix 1 quart of broth with flour gradually, stirring well.

  3. Heat the mixture in a pan, stirring until it boils, then let it boil briefly.

  4. Serve the meat on a dish, strained sauce over it, and add optional garnishes.

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

What each ingredient does

Barley
Its starch and fiber thicken the broth and give the soup body and a chewy texture.
Beef shin or leg
Collagen from the connective tissue melts during long simmering, enriching the broth and softening the meat.
Onions
Release sugars and aromatic compounds into the broth, adding savory sweetness and depth.
Celery
Adds aromatic flavor and a fresh, vegetal note to the broth.
Flour
Starch granules swell when heated with liquid, thickening the strained broth into a sauce.

The step that matters

Adding the flour to the broth. Flour clumps if dumped in at once. Mixing it gradually into cool broth and stirring well disperses the starch, so it thickens evenly once heated.

Swap the capers

The recipe marks capers as optional. How well each one fits the dish's main ingredients (barley, beef, onion, celery, turnip, flour):

  1. Capersthe original
  2. Thymefits about as well
  3. Turmericfits about as well
  4. Parsleyfits about as well

Fit is the average pairing score against barley, beef, onion, celery, turnip, flour. Candidates are from the same food group and used in at least 100 recipes.
