The secret ingredient to making crispy carrot (or sweet potato) chips is a little bit of cornflour! Too much and they will be pasty, too little and they won't get as crispy. Eat them right away, they soften after too long out of the oven. Be warned, you will be done in 3 minutes flat so you might want to make a double batch because they are so addictive! You can just buy Cajun seasoning if you don't want to make the spice mix below.
