Abstract
A package of popcorn which is ready for popping in a microwave oven of from about 600 to 1,400 watts capacity is composed of a flexible and expandable package e.g. a gussetted bag formed from paper. The package is sealed to permit internal pressure to develop to expand the bag so that the corn has sufficient space for the increased volume assumed after popping. The charge of popcorn in the bag is uniformly mixed with about 1 to 5 parts by weight of a shortening for each 8 parts by weight of corn. The shortening comprises an edible solid or liquid fat and the package contains salt for flavoring.
