Kidney and Pickle Soup

Ingredients

Directions

Prepare the kidneys and vegetables

  1. To prepare the kidneys, remove their fat and membrane, cut in half, cover with cold water, and let soak for 6 hours, changing the water every 2 hours.

  2. Discard the last water. While the kidneys are soaking, cut the carrot, parsley, celery root, and onion into julienne strips.

Make the soup

  1. In a 4-quart pot, bring 2 quarts of water to a boil.

  2. Add the kidneys (or the giblets, if you are using them), julienned vegetables, 1 teaspoon salt, and the peppercorns and bay leaves, and bring to a boil again.

  3. Lower the heat and simmer, partially covered, for 30 minutes.

  4. Meanwhile, peel the potatoes and cut into 1‑inch cubes.

  5. Strain the stock, discarding the vegetables.

  6. Cut the kidneys into 1/4‑inch slices and return to the stock, adding the potatoes and rice.

  7. Cook slowly, partially covered, for 20 minutes, then add the pickles and simmer 5 minutes more.

  8. Turn off the heat, cover completely, and allow the flavors to mingle for 5 minutes.

Finish and serve

  1. Blend the sour cream with 1 cup of soup and stir it back into the pot, then taste for seasoning.

  2. Serve in a warmed tureen, sprinkled with tarragon.

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

What each ingredient does

Kidneys
Provide the main meaty texture and rich, distinctive flavor of the soup.
Potatoes
Soften into cubes that thicken the broth and give it body.
Long-grain rice
Absorbs liquid and releases starch, thickening the soup slightly.
Sour pickles
Add sharp acidity that balances the rich broth and kidneys.
Sour cream
Adds creamy richness and a tangy, mellow finish to the soup.

The step that matters

Soaking the kidneys. Soaking for several hours with frequent water changes draws out blood and strong urinary odors, so the kidneys taste clean rather than bitter or gamey.

Swap the onion
