Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Catfish
- The main protein, which cooks through in the hot fat while its coating crisps.
- Flour
- Forms a dry coating that helps the surface brown and crisp when fried.
- Eggs
- Bind the coating so it sticks to the fish.
- Lard
- Fat for frying that browns the coating and transfers heat evenly.
The step that matters
Fry in hot lard until light brown. Hot fat sets the coating quickly and browns it before the fish overcooks, while cool fat soaks into the coating and makes it greasy.
