Why it works: Fish and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,488 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Fried White Fish
Ingredients
Directions
Prepare
Clean and dry the fish, then salt it inside and out.
Roll the fish in cracker flour or bread crumbs, then in the beaten egg seasoned with a pinch of salt.
Fry and serve
Fry in very hot butter until golden brown on both sides.
If the fish is large, split it lengthwise and cut into pieces about 3 inches wide.
Serve with catsup and slices of lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Provides the main protein that is cooked and served whole or in pieces.
- Cracker flour or bread crumbs
- Forms a dry coating that helps the crust brown and crisp when fried.
- Beaten egg
- Binds the crumb coating to the fish so it stays on during frying.
- Butter
- Conducts heat for frying and adds browning and a rich flavor to the crust.
The step that matters
Frying in very hot butter. If the butter is not hot enough, the coating absorbs fat and turns greasy instead of browning quickly. Hot fat sets the crust fast, so the fish cooks through while staying crisp outside.
