There are 2 ways of frying known to cooks as (1) wet frying, sometimes called French frying or frying in a kettle of hot fat; and (2) dry frying or cooking in a frying pan. The best results are undoubtedly obtained by the first method, although it is little used in this country. ["The Household Cook Book," Chicago, 1902]

In the Upper Midwest of the U.S., sometimes called, with greater accuracy, American fries (1950), and briefly during a period of mutual ill feeling, an attempt was made at freedom fries (2003; compare liberty-cabbage for sauerkraut during World War I).
