Add vinegar, peri peri seasoning, ginger garlic paste, salt and black pepper to the fish and mix. Then sprinkle the flour and coat around.
In one bowl mix together panko crumbs, all-purpose flour and dried parsley.
In another bowl whisk the egg with milk.
First dip the fish in egg mixture then coat with panko crumbs. Keep aside. You can freeze these fish nuggets at this point.
For Deep Frying: Heat oil in a deep pot. Fry fish nuggets on medium heat till golden on each side. Drain on a paper towel.
For Air Frying: Place the fish nuggets in a single layer in the air fryer basket. Spray with some olive oil. Air fry for 10-15 mins at 180 C till golden and crispy. Don't forget to flip midway.
For Baking: Bake at 200C for 15-18 mins.
Serve the fish nuggets with tartar sauce or a dip of your choice. You can also sprinkle some extra peri peri seasoning on top.
Notes
Use crushed cornflakes or breadcrumbs if you don't have panko crumbs.
