Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brook trout
- Provides the main protein; its flesh cooks through while the coating crisps.
- Bread crumbs
- Form a crisp, golden coating that protects the fish during frying.
- Butter
- Adds rich flavor and helps the coating brown as it fries.
- Lard
- Fat for frying that tolerates high heat and gives a crisp, even browning.
- Onion
- Listed as an ingredient but not used in any step, so its role is not stated.
The step that matters
Frying the coated fish. Medium heat must brown the coating before the fish overcooks. Fat that is too cool soaks into the crumbs, while too hot a pan can scorch them before the fish is cooked through.
