Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Provides the main protein and the flesh that is cooked and served.
- All-purpose flour
- Forms a thin coating that browns in the butter and helps the fish keep its crust.
- Milk
- Moistens the surface so the flour coating adheres evenly to the fish.
- Butter
- Conducts heat for frying and adds richness and browning to the crust.
The step that matters
Frying until golden brown. Flour-coated fish can scorch before it cooks through if the heat is too high. Medium heat lets the coating brown gradually while the flesh cooks evenly and stays moist.
