A potato chip (American English) or crisp (British English) is a thin slice of potato that has been deep fried, baked, kettle-cooked, or popped until crunchy. Potato chips are commonly served as a snack, side dish, or appetizer. The basic chips are cooked and salted; additional varieties are manufactured using various flavorings and ingredients including herbs, spices, cheeses, and artificial additives. (source)
