Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture into a smooth paste and give the coating its set.
- Bread crumbs
- Absorb moisture and add body so the croquettes hold their shape.
- Vermicelli
- Forms a crisp, browning outer coating when fried.
- Fat
- Conducts heat for frying, browning and crisping the outside.
The step that matters
Fry the croquettes in hot fat until they are a nice bright brown. If the fat is not hot enough, the croquettes absorb excess fat and turn greasy before the coating browns. Hot fat sets and crisps the coating quickly, keeping the inside moist.
