Abstract: A method for preparing a food product having a predetermined perimetrical shape from a moldable mixture of food product ingredients. The method, in a preferred form, comprises the steps of providing a plurality of substantially planar panels that can be removably interconnected; bending and interconnecting the panel members to form a panel assembly having the desired perimetrical shape; placing the panel assembly on a bottom member to form a cavity; sealing the intersection between the panel assembly and the bottom member; pouring the moldable food product into the cavity and processing the food product to cause it to solidify; and thereafter, removing the panel assembly from the food product.
