A few days ago I soaked a bunch of casings in water in my fridge to stuff my gyro sausage. I soaked way too many for what I actually needed. Can they be stored in that water in the fridge for an extended period of time or should I return them to their original package with the salt solution? Thanks! Also, if I don't return them to the original package with the salt solution, how long can I let them stay in the soaking container as I might make some more sauage in the next couple or days. Thanks!
