"The biggest secret to getting the kale super-crisp is to dry them in a salad spinner. If there is moisture on the leaves, the kale will steam, not crisp. Also, do not salt the kale until after they have come out of the oven. If you salt beforehand, the salt will just cause the kale to release moisture...thus steaming instead of crisping. I've also found that the convection setting on my oven works really well too - I set the convection on 325F and bake for about 10-15 minutes. Have fun with this recipe, I sometimes mix the salt with Cajun or Creole seasoning...."
