Expandable volume food preparation and forming tool apparatus and method

The invention is an expandable volume food preparation tool for precisely and quickly forming a quantity of dough into a plurality of uniform dough blocks having a predetermined volume and shape. Included therein is a base plate having a base opening disposed therethrough. The base opening is defined by a continuous substantially vertical interior base sidewall arranged to define a predetermined outline shape. A base volume is defined by the void enclosed by the base sidewall. To enable the user to manipulate the base plate, a handle is mounted to the base plate. Additionally, a removable primary extension plate is mounted to the base plate. The primary extension plate includes an extension opening defined by a continuous, substantially vertical, interior extension sidewall arranged to define an outline shape substantially identical to the outline shape of the base opening. An extension volume is defined by the void enclosed by the extension sidewall within the primary extension plate. In the preferred embodiment, the primary extension plate is removably mounted to the upper surface of the base plate such that the interior extension sidewall is aligned with the base sidewall.
