Ox-Kidney Saute

Ingredients

Directions

Prepare the kidney

  1. Cut the ox kidney in half lengthwise, then slice each piece into thin slices.

  2. Melt the butter in a sauté pan, then add the kidney slices.

  3. Season with salt and pepper, then fry until lightly browned, shaking the pan frequently.

  4. Remove the slices and let them drain.

Make the sauce and finish

  1. In a saucepan, combine the white wine, salt, and pepper, then boil until reduced to one-fourth its original quantity.

  2. Return the kidney slices to the sauté pan, dredge with flour, and fry for 2-3 minutes.

  3. Add the reduced wine, broth, and water, then boil for 5 minutes.

  4. Stir in the chopped parsley and serve hot.

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

What each ingredient does

Ox kidney
Is the main protein, cooked quickly so it browns outside and stays tender inside.
Butter
Carries the frying heat and adds fat, helping the kidney slices brown.
French white wine
Reduced by boiling to concentrate its flavour and acidity into the sauce.
Flour
Dredging coats the slices so they brown and help thicken the pan liquid.
Broth
Adds savory body and liquid to the sauce.

The step that matters

Fry the kidney until lightly browned, shaking the pan. Kidney overcooks quickly and turns firm and rubbery if held too long over heat. Frequent shaking keeps the slices moving so they brown evenly without drying out, while the inside stays tender.

Swap the parsley

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

  1. Thymefits about as well
  2. Parsleythe original
  3. Tarragonfits about as well
  4. Marjoramfits about as well

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