SUPER IDEA !!! ... mix up each batch and place each pie filling in it's own freezer bag. I then place the freezer bag in a pie pan and place it in the freezer to freeze in that shape. Once the filling is frozen, I take it out of the pan and store the fillings in stacks in the freezer. When I want to make a pie, all I have to do is unwrap a filling, plunk it into the crust, and bake
If you ever intend to decorate a cake or cookies you need to see this video about how to fill your icing bag... LIFE CHANGING. Why didn't they teach THIS in my Wilton class???
If you want to pipe 2 different colors of icing onto something... fill 2 separate icing bags with icing - butter cream and chocolate. Then insert BOTH of them into one bag with tip attached to the coupling. Now when you squeeze - both come out at the same time!
