I make a Crispie type cake, but with my own homemade ingredients, Mallows,etc when I make it with shop bought Marshmallows etc it lasts for weeks, when I make it with my own ingredients it goes soft/dry, the crispies loose their crisp and the gooeyness goes. How do I solve this? Would thicker packaging work? or vacuum sealer. At the moment they are just on trial and are being ept in thin "boil in a bag" vacuum packaging for home use. Can anyone give me any advice that might help me please. Thank you Sarah

  • I'm sorry, I don't know of Crispie type cakes. Can you post a recipe?

  • Yes, however, I am English, so over here we use a C instead of a K. :)

    Sounds like you've got water migrating from your home-made marshmallow to your puffed rice. Packaging won't (can't) solve that.

I usually store them in an airtight container, with wax paper underneath each layer. They keep very dry stored like this. It could be that your bag is not sealing 100%
