pre-heat your oil to 350-375. prefere outside in a turkey cooker or an electric deep fryer. i use soy oil but, whatever you are happy with. .take fillets that have drained in a strainer..no egg wash, no milk, no water, no dipping. just plain fish, moist..get a cajun batter bowl or similar..mix 1/2 corn starch and 1/2 masa (corn flour). .add fish (pork-beef-chicken-whatever).shake, flip, shake again..deep fry..trust me, it works.
A 50/50 mix with corn starch? Am I reading that correctly?
