The term 'potato tool' refers to two kitchen utensils used for preparing potatoes. The first is a ricer, which is a device with a handle and a metal plate with small holes that is used to mash potatoes into a fine, smooth texture. The second is a PEELER, which is a tool with a sharp blade that is used to remove the skin from potatoes. Both of these tools are essential for making mashed potatoes, potato salads, and other dishes.
