Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Cod and Parmesan Cheese
Ingredients
Directions
Prepare the cod
Remove the skin and bones from the cold cod and break it into convenient-sized pieces.
Make a white sauce and warm the cod pieces in it, then drain them.
Coat the fish
Dip each piece in beaten egg, then coat with bread crumbs and Parmesan cheese.
Cook and serve
Thicken the gravy with arrowroot or flour and keep it hot in the saucepan.
Fry the coated fish pieces in hot butter until lightly browned, about 8 to 10 minutes.
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
