The pieces of meat are placed on a tall vertical spit, which turns in front of a source of heat, usually an electric broiler. If the meat is not fatty enough, strips of fat are added so that the roasting meat remains always moist and crispy at the same time. The rate of roasting can be adjusted by varying the strength of the heat and the distance between the heat and the meat, allowing the cook to adjust to varying rates of consumption. The outside of the meat is sliced vertically in thin, crispy shavings when done.
