Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Catfish
Provides the main protein; cutting and removing the backbone make it lie flat for even frying.
Flour
Forms a dry coating that browns in the hot fat and gives the fish a crisp exterior.
Hot lard
Conducts heat to cook the coating quickly and drives browning and crispness.
Beaten egg
Helps the optional coating or crumbs adhere to the fish in the variation.

The step that matters

Frying in hot lard until light brown. If the lard is not hot enough, the coating absorbs fat and turns greasy instead of crisp, while overcooking can dry the fish. Thoroughly dried fish also prevents oil spatter and keeps the coating from steaming.
