Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton kidneys
- Form the main body of the dish, with a rich, meaty flavor when browned and stewed.
- Macaroni (in the method)
- Provides a tender starchy base that soaks up the gravy and holds the kidneys.
- Gravy flavored with tomatoes
- Supplies moisture and a tangy, savory sauce that keeps the kidneys tender as they stew.
- Butter
- Fat for frying the kidneys, promoting browning and a richer flavor.
- Parmesan cheese
- Adds salty, savory depth and a sharp flavor to the finished dish.
The step that matters
Stew the fried kidneys in the gravy. Kidneys turn tough and rubbery if overcooked. Gentle, moderate simmering in the gravy keeps the proteins tender and lets the sauce absorb their flavor.
