Macaroni with Tomatoes and Kidneys

Ingredients

Directions

Prepare the macaroni

  1. Boil the macaroni in veal broth until tender, then strain and keep warm.

Make the kidney gravy

  1. Skin the mutton kidneys and fry them lightly in butter.

  2. Remove the kidneys from the pan, mince them finely, and set aside.

  3. In the same pan, make a gravy by adding brown flour, rich gravy, minced shallots, and cayenne.

  4. Stew the minced kidneys in the gravy for 10 minutes.

Combine and serve

  1. Mix part of the warm macaroni into the gravy and toss for a few minutes.

  2. Serve the mixture on a hot dish, arranging the remaining macaroni on top.

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

What each ingredient does

Mutton kidneys
Provide the main meaty flavour and a tender, rich texture when stewed in the gravy.
Macaroni
Forms the starchy base that absorbs the gravy and gives the dish its body.
Brown flour
Thickens the butter and pan juices into a gravy and adds toasty, browned flavour.
Butter
Adds richness and carries flavour when frying the kidneys and building the gravy.
Shallots
Add a mild, sweet onion-like aroma that deepens the gravy.

The step that matters

Frying the kidneys lightly. Kidneys turn tough and rubbery if overcooked, so they should be cooked only briefly before mincing and finishing in the gravy.

Swap the shallot

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

  1. Leekfits about as well
  2. Shallotthe original
  3. Chivefits less well
  4. Turnipfits less well

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