The white fish fillets should be divided into 2 inch wide pieces.

Heat the water until it boils. Stir in the salt and sugar until they are completely dissolved.

Lower the fish pieces into the boiling water using tongs.

Cook for approximately 7 minutes, or until the fish starts to flake.

Remove the fish using a skimmer, then add it to the bowl containing the melted butter.

After removing from the butter, rub the fillet pieces with lemon juice.

Serve warm.
