  • Patent number: 6506041
    Abstract: Disclosed is a perogie maker for producing individual perogies from a single layer of dough. The perogie maker consists of round, hollow cylinders attached to one another at the ends of the cylinders by rotatable hinges. The cylinders have alternating raised and lowered notches, and a ridge surrounding the outside of at least part of the cylinder which is capable of cutting through dough. When handles attached to the cylinders are brought together the raised notches close on lowered notches and a layer of dough is folded as such to produce sealed perogies, with excess dough being trimmed by the ridge.
