Very simple and really crunchy. I found this recipe awhile ago and jotted it down. I like mine extra spicy so I soak my cut potatoes in hot sauce for a few seconds before shaking them in the dry batter :)
Place cut potatoes into a large bowl of cold water. Soak for 10 minutes. In a large resealable plastic bag, combine the corn flour, corn meal, and Cajun seasoning. Shake the bag to blend. Drain the potatoes, but leave them wet. Place the fries in the plastic bag with the seasoning, and shake to coat.
Heat the oil in a deep-fryer to 375°F.
Cook fries in hot oil for 7 to 10 minutes, or until golden brown. Remove from the fryer to paper towels to drain. Season with a small amount of salt.
