Clean fish with water and dry thoroughly with kitchen towels.

With a sharp knife, make two shallow parallel incisions to the fish on each side.

In a bowl, mix your flour and a pinch of table salt.

Gently dust a layer of the flour mixture on your fish, shaking off any excess.

In a wide frying pan, apply enough oil to coat the surface of your fish and heat it up on medium heat for approximately 3 minutes.

Carefully lay your fish away from you into the oil - it should gently sizzle. Leave it untouched for approximately 4-5 minutes.

With a spatula, gently flip the fish away from you to fry the other side for approximately 3-4 minutes. Once cooked, remove fish onto a cooling rack - use a cooling rack to prevent the bottom side of the fish from steaming.

Discard the oil used. In the same pan, add your soy sauce and sugar and let it come to a gentle simmer. Leave it to simmer for 3 minutes for all the sugar to be dissolved into the sauce.

While it is still hot, glaze the fried fish with your sauce and immediately serve with some hot rice!
