If you only need to store it for a few days, I would just put it in tin foil and put it in a dark place, like a cabinet. I have heard that for long term storage the fridge is best, although I would worry about condensation, even if in an airtight container (can condensation form on the inside of a jar if it's in the fridge? embarrassingly, I'm not sure).
Like rolltide said, just keep it wrapped in some foil, in a nice cool place. For long term storage, the freezer would be the best option. I don't know much about that though.
