Dark Hero

I would really like to see another way to preserve food. There are many different methods throughout history that have proven somewhat effective. Ice Boxes, zeer pots, even cellars. I think it would be a really cool semi-late game item that you could make with a high carpentry skill or what not, and the refridgeration value wouldn't be as high as actuall refridgerators. I don't know what everyone else thinks, I just thought it might be a good idea.
