Rehydrating them in a resealable zipper bag will give you the added convenience of fitting them in a small space in your fridge.
Use a fairly large quantity of water, so that the Shiitake are completely submerged. You can add more water if needed later. If you have a lot of liquid leftovers, you can use it to make a broth for soup, etc.
