  • Patent number: 4337275
    Abstract: An improved meat product is disclosed, which comprises a slab of ground meat, shaped to resemble a steak. On both sides of the slab is a set of grooves. The grooves on a particular side are parallel to each other, but the grooves on one side are oriented in a different direction from that of the grooves on the other side. This arrangement assures that the meat particles, before cooking, will be intertwined, thereby improving the similarity in texture to an actual steak. After cooking, the meat product will have parallel darkened bands on its two sides, thereby enhancing its visual similarity to a charcoal-broiled steak.
