ABSTRACT:
A device for serving popcorn and the like comprising a bowl with a generally concave interior surface and a series of horizontal, circumferential ridges carried by the bowl, each with a face on the radially inward side of the ridge for resisting tangential movement of a first layer of popped corn in the bowl. The faces are approximately perpendicular to the interior surface of the bowl. When movement of the first layer is resisted, movement of all the popped corn in the bowl is resisted because popped corn kernels tends to interlock. The faces of the ridges need only be as high as one-third the height of a popped kernel of corn. Preferably, thereby are at least two ridges, a first ridge at the generally flattened central portion of a bowl and at least one additional ridge radially outward of the first ridge.
