Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms a light coating that turns crisp and golden when fried.
- Oil
- Transfers heat evenly to cook the fish and brown the flour coating.
The step that matters
Frying the coated fish until golden brown. The fish must be dry before coating and the oil must be hot. A dry, hot surface lets the flour crisp and brown quickly, while wet fish or cool oil lets the coating absorb oil and turn greasy and soggy.
