I have considered making them but never have. I bought some at Costco that are supposed to be fresh. I think they are partially cooked. They were really good, but there are way too many in a package. I know the ones from the store are so full of junk and preservatives. I found a package in my closet that expired 2 months ago. I store them on the shelf where they are under my bread, it is high enough up that I can't see them. They still seemed fresh enough to eat and no mold. I wonder how much preservatives are in them?????
