Field of Invention The present invention relates to food preparation devices. More particularly, the present invention relates to machines and apparatuses for preparing cooked foods, especially dumplings. 2. Discussion of the Background People have been making dumplings for years. In a typical process, the cook uses various cooking utensils to extrude soft batter and the like into a pot of hot liquid, such as water or oil. These conventional utensils generally include a partially perforated (e.g., holes distributed over half a surface) or totally perforated (holes distributed over an entire surface) pan or a die through which a cook extrudes pre-prepared through the perforated plates, or surfaces, by applying a force to the batter, perhaps using a tool to assist in applying the force. For example, U.S. Pat. No. 3,452,688 describes a dough extruding apparatus having an extrusion die mounted directly above a cooking vessel. The dough is extruded through the die by a force exerted on a pressure plate by manually pushing handle downwardly. U.S. Pat. No. 1,461,504 describes a macaroni die that includes a plurality of plates secured together. The die is adapted for producing food products with irregular shapes. U.S. Pat. No. 4,452,581 describes a cooking utensil having a pan with a food holding area and an array of holes making up the extrusion area for batter that is pressed therethrough. The pan is removably mounted on a cooking vessel by way of a single removable clamp that holds the pan in place during the batter extrusion process. The present inventor identified a number of limitations with this convention device. For example, the use of a single clamp provides insufficient stability for a pan, thus creating a safety hazard because the device is used over boiling water. Furthermore, the device cannot be universally used over a wide variety of cooking vessels because the clamp is not adapted for use with cooking vessels having, for example, a curved lip. The utility of this device is also limited because the single clamp mounting arrangement of the pan on top of cooking vessel leaves excessive exposed surface area of the boiling water, and thus creating a steam scolding hazard for the cook. The present inventor also recognized that this conventional device offers no provision for a handle, making the pan awkward to manage. Lastly, certain batter mixtures are very sticky and can easily lift up the whole cooking utensil and force it to fall into the boiling water, thus creating another safety hazard. BRIEF SUMMARY OF THE INVENTION An object of the present invention is to overcome the above-identified and other deficiencies with conventional cooking apparatuses. As recognized by the present inventor, it would be advantageous to provide a one-piece cooking utensil that would have a radially-extended, continuous circumferential rim with one or more extended supports and a handle over the cooking vessel to provide safety and speed to facilitate dumpling making. It would also be advantageous to provide a two-piece cooking utensil having a detachable holder and a partially or completely perforated pan that can be universally placed on top of any commonly used cooking vessel regardless of lip configurations that are commonly available. It would also be advantageous if the cooking utensil could be supported at multiple points on top of the cooking vessel to provide stability and safety for the utensil during operation. It would also be advantageous to cover or significantly reduce the exposed surface area of the boiling water around the cooking utensil to protect the cook from steam scolding during the extrusion process. It would also be advantageous to have a handle for the holding device to provide additional support, quick and safe removal of the cooking utensil from the cooking vessel. It would also be advantageous to provide a holding device for the perforated pan that would be removable and easily adaptable to different size perforated pans and at the same time provide a handle and one or more supports for safety and speed to the dumpling making process. It would also be advantageous to provide a removable holding device that would tightly snap around the perforated pan that would prevent the pan from coming loose during dumpling making. It would also be advantageous to provide a two piece cooking utensil having a detachable holder and a partially or completely perforated pan that can be universally placed on top of any commonly used cooking vessel regardless of lip configuration. The present invention addresses these, and other, needs by providing a continuous circumferential pan holder for the partially perforated pan, preferably circular but it can be of rectangular or other geometric shape, on top of the cooking vessel and thereby provide total support all the way around the pan, stability and safety during the extrusion process. Another object is to provide a universal pan holder that can be used on all common cooking vessels typically ranging from 7.5 inches to 19 inches in diameter, or any pot diameter by matching an appropriate size holder for the pan. Another object is to provide a pan holder with one or more support points that can be easily attached to other perforated pans having different hole sizes and patterns to facilitate smaller or larger dumpling production. Another object is to provide a handle for the pan holder outside of the cooking vessel surface area to prevent the homemaker from steam burns and to provide additional stability and mobility during dumpling making. In addition, the handle would provide a way to lift the perforated pan from the cooking vessel and help with the occasional stirring of the dumplings in the boiling water or soup. In a first embodiment, an all-in-one piece, or integrated, stamped or molded cooking utensil includes a partially perforated pan having a narrow rim, radially extended outward continuously and circumferentially. The device also has one or more supports and a handle that protrudes beyond the outermost diameter of the rim. The resultant cooking utensil is a one piece stamped (forged, molded or cast) assembly, whereby the extended rim and outer supports are flat and become an integral part of the perforated pan. The cooking utensil is made to conveniently rest on top of most common cooking vessels. A second embodiment provides a universal and removable-type one piece stamped, forged or molded flat holder, of sufficient structural strength to hold, a perforated pan. This holder, has a void in its center (or other interior portion) to accommodate the perforated pan, has a continuous and circumferential wide rim and has one or more supports and a handle as an integral part of the assembly. This universal pan holder can be made from sheet metal such as aluminum or stainless steel, heat resistant plastic or any other suitable food-grade material. A flat holder fits directly underneath the pan rim and provides continuous circumferential support as well as one or more extended support points over a cooking vessel similar to all-in-one utensil described above. This embodiment of the invention is suitable to be packaged as part of a kit to facilitate the interchangeability of several pans with different perforated hole sizes, shapes and layouts to accommodate a partially perforated pan having a refill area and an extrusion area. A third embodiment of the invention provides a separate removable and universal "wire-type" pan holder made from round stainless stock and bent into an appropriate pattern to provide one or more support points. This embodiment may also be packaged as a part of a kit to facilitate the interchangeability of several pans with different hole sizes, shapes and layouts having a refill area and an extrusion area. In conjunction with the use of this "wire-type" holder, the vertical sides of the perforated pan are fitted with multiple detents whereby the holder is slipped over them and is locked between the detents and the rim of the pan. The resultant holder assembly provides multiple support points with handle to operate cooking utensil safely and quickly. A fourth embodiment provides a separate removable and universal "vertical metal band-type" pan holder made from flat stainless steel stock, preferably 1/16 in.times.3/8 in, bent vertically into an appropriate pattern to provide one or more support points. This embodiment may also be packaged as part of a kit to facilitate the interchangeability of several pans with different hole sizes and layouts having a refill area and an extrusion area.
