I'm making a not-to-be-eaten decoration for a cake out of gum paste (I bought the pre-made stuff) and I want it to be totally dry and hard. I know I can make it as much in advance as I'd like, but my question is how can I store it so that the humidity doesn't make it soft again... or will gum paste, once dry, remain that way even if stored in an airtight container?
I would like to keep it in a plastic box for about a week after it's dry before I need to use it. Will fairly thin pieces remain dry and hard stored that way?
thanks in advance!
I would think that you should be fine. As long as the plastic box is kept airtight, I don't see how the moisture in the air would get in the box. I've never had a problem with gumpaste becoming soft again, but I live in southern California, and we're pretty much humidity free.
Just make sure the airtight container is left in a cool place. One time I tried to save some fall gumpaste leaves and I stored them in an airtight container also but didn't think to keep it in a cool dry place and they had become soft overtime and lost there pretty shape.
If you can get your hands on a couple of those little packetts that often come in shoe boxes (that absorb moisture) it would be helpful to add them to your stored gp.
I have some gumpaste pieces I made just over a year ago stored in a zip lock baggie, they are still hard as a rock. But I did have some fondant ones that I made and stored in a plastic container for a few months, when I went back they were all gooey. I am guessing this was because there was still some moisture in the fondant when I stored it.
I'm guessing you don't have a kiln? Silica gel packs (I get mine from Amazon...actually, I get EVERYTHING from Amazon) in a ziploc bag and the bag in a container and you should be fine.
thank you all for your responses! That's what I thought, but before I get to work on it I just wanted to be sure it would stay hard and dry.
