There is presented a method and systems and methods for packaging foods with disparate water activity values, whereby an environment is presented to preserve substances, such as foodstuffs, by preventing unwanted water transfer between them within a multi-compartment package. Such a container may include a first inner compartment and a second inner compartment defined within an interior volume of the container; an opening mechanism to provide access to the contents of the two or more inner compartments; and wherein the first and second inner compartments are sealed and segregated to prevent migration of water from a first provided foodstuff stored within the first compartment to a second provided foodstuff stored within the second compartment.
