Mix the flour and seasonings together in a space saver bowl.
Shake the eggs, water and milk powder together in the quick shake. Add to the dry ingredients and mix well with paddle scraper. The mixture should have consistency like pancake batter - add extra water if it's too thick.
Heat the oil in a large pot.
Coat the fish in the batter and fry lightly, until golden brown. Drain the fish on paper towel.
Notes
Do not fry too many pieces of fish at once, or the temperature of the oil will drop and the fish will absorb more oil and become soggy and unappetizing.
