At this stage you can stick your potato gratains in the fridge until you need them. Storage life is good since there is no or little oxygene in the package. When it is time to cook you simply boil a large pot of water. Stick as many packages in as you think you will need and let it boil for 60-180 minutes. Since the package is sealed off there will be no evaporation and the gratain won't go dry.

If you are planning to serve the gratains over a long period of time you put them in the boiling water with an interval.
