Shape and coat

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Minced fish
- Forms the main body of the croquettes and provides their savory flavor.
- Egg
- Binds the mixture together and helps the coating adhere before frying.
- All-purpose flour
- Thickens the mixture so it holds its shape when rolled into balls.
- Milk
- Adds moisture to the mixture, keeping the croquettes tender inside.
- Bread crumbs
- Forms a crisp outer crust that browns during frying.
The step that matters
Fry the croquettes in hot oil until golden brown. If the oil is not hot enough, the croquettes absorb excess oil and turn greasy, while the coating may not set before the inside overcooks. Frying in hot oil seals the crumb crust quickly and gives even browning.
