Another type of potato chip (most famous for the Pringles brand) is extruded, which is to press the mashed potato into a common sheet before frying. This allows the potato chips to be very uniform in size and shape and easy to pack in a cardboard cone. In the United States, the legal term (de jure) is “crisps,” but this is not universal. In contrast, the potato chips in Europe are called “potato chips” to distinguish them from the traditional “crisps”.
The success of the potato chips also gave birth to cornflakes, and the Fritos, CCs and Doritos brands dominated the market. A variety of root vegetables such as parsnip, rutabaga and carrot are also made into "Swam chips". Rice and cassava are extruded into Japanese fried rice (rice).
