An apparatus is provided for forming a plastic food material into bodies having an arcuate top and a flat bottom. The apparatus includes a cylindrical nozzle body for receiving the food material from a pressurized source. In the periphery of the nozzle body is included a food material forming orifice having a plane lower bounding surface contiguous thereto which lies within the nozzle body in a plane inclined downward towards the exterior of the nozzle body. A cutter sleeve is mounted on the nozzle body and moved relative to it to selectively cover and uncover the orifice. The apparatus imparts a curved contour to the top of the pressurized food material escaping from the orifice, while the inclined plane lower bounding surface imparts a flat bottom to the material.
