French fries (North American English), chips (British English and other national varieties), finger chips (Indian English), french-fried potatoes, or simply fries, are batonnet or allumette-cut deep-fried potatoes of disputed origin from Belgium or France. They are prepared by cutting potatoes into even strips, drying them, and frying them, usually in a deep fryer. Pre-cut, blanched, and frozen russet potatoes are widely used, and sometimes baked in a regular or convection oven; air fryers are small convection ovens marketed for frying potatoes..

The potatoes are prepared by first cutting them (peeled or unpeeled) into even strips, which are then wiped off or soaked in cold water to remove the surface starch, and thoroughly dried. They may then be fried in one or two stages.
