Cod and Parmesan Cheese

Ingredients

Directions

Prepare the cod

  1. Remove the skin and bones from the cold cod and break it into convenient-sized pieces.

  2. Make a white sauce and warm the cod pieces in it, then drain them.

Coat the fish

  1. Dip each piece in beaten egg, then coat with bread crumbs and Parmesan cheese.

Cook and serve

  1. Thicken the gravy with arrowroot or flour and keep it hot in the saucepan.

  2. Fry the coated fish pieces in hot butter until lightly browned, about 8 to 10 minutes.

  3. Pour the sauce over the fish and serve hot.

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

What each ingredient does

Cod
Forms the flaky main body of the dish, cooked through by frying and warming.
Butter
Fat for frying that carries heat and helps the coating brown.
White sauce
Keeps the cod moist while warming and forms the gravy served over the fish.
Beaten egg
Acts as a binder so the bread crumbs and cheese stick to the fish.
Bread crumbs
Forms a crisp coating that browns when fried in butter.
Parmesan cheese
Adds savory flavor to the coating and helps it brown.
Arrowroot or flour
Thickens the sauce so it clings to the fish when served.

The step that matters

Fry the coated fish pieces in hot butter. The butter must be hot enough to brown the coating quickly. If it is too cool, the crumbs absorb fat and turn greasy while the fish overcooks. Gentle, even heat keeps the fish moist inside.

Swap the arrowroot
