Abstract
Apparatus and method for popping high yield popcorn using a bag having a substantially rectangular cross section as manufactured using a conventional bag machine. A base supports the bag on edge with at least one joining panel being inclined such as, for example, at 45.degree.. Whether the bag is initially unfolded or unfolds as a result of internal pressure caused by some kernels popping, a horizontal elongated V-shaped trough is formed as the lower-most region of the bag due to the supporting orientation of the base. Kernels form in a clump in the nadir of the trough thereby enhancing the yield of the popping, and kernels disturbed from the clump by popping kernels are directed back to the clump by the inclined walls of the bag.
