Ingredients
Directions
Prepare the filling

Make the batter

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the croquettes once pounded smooth.
- Egg
- Binds the mixture and helps it set firm when cooked.
- Flour
- Thickens the batter so it holds the croquettes together.
- Milk
- Adds moisture to the batter, keeping the croquettes tender.
- Essence of anchovies
- Adds a salty, savoury flavour to the fish mixture.
The step that matters
Frying the balls until golden brown. Oil that is too cool lets the balls soak up grease and fall apart, while oil that is too hot browns the outside before the centre is cooked through. Gentle, steady heat gives an even golden crust.
