Originally classified as Triticum turgidum var. polonicum (Polish wheat), but also suggested by some to be Triticum turgidum ssp. turanicum (oriental or Khurasan wheat), or being in fact Triticum turgidum var. durum (durum wheat). A type of wheat marketed by Kamut International, Ltd. under the trademark Kamut, while its official designation by the United States Department of Agriculture is QK-77.
QK-77 is a large durum wheat-like grain that requires several hours of simmering to soften. Is an ideal ingredient for use with slow cookers due to its culinary nature.
