The first McDonald’s French Fries were made from fresh potatoes in restaurants, with employees peeling, cutting, washing, blanching in oil, and conditioning the potatoes before finishing frying them. The first cooking oil was an animal-based shortening and the blend specific to McDonald’s.
Early – Mid 1960s:
McDonald’s Food Scientist Ken Strong and Food Researcher Edwin Traisman patented the McDonald’s frozen French Fry process which enabled McDonald’s potato suppliers to obtain the same great taste, color and texture characteristics that came from in-store preparation with more consistency.
Early – Mid 1970s:
McDonald’s potato supplier partners perfected French Fry production with new technologies like the steam peeler, cutting systems, and Automatic Defect Removal equipment, enhancing quality and efficiency.
