Kettle Cooking

What is with this flavoring? It's everywhere. Kettle corn, kettle-cooked chips... While they are tasty one of my coworkers mentioned that he fears for his teeth when he eats kettle chips. Since I have a bit of dental work, I share his concerns. Calling kettle-cooked chips "crisp" is a bit of an understatement. A better description might be "tempered" or "forged".
