I would like to mail already mixed royal icing. I use meringue powder instead of real egg whites, and I just wanted to know is it safe to ship royal icing? Would there be any problems with the heat during shipping? I store my royal icing in airtight containers with plastic wrap so it doesn't dry out. Any advice would be greatly appreciated

I can't see a problem with it shipping. I would probably go ahead and put the bowl in a ziplock bag, and then just some packing peanuts in the box to keep it from getting banged around and broken. Just be sure to stir it really will be for using it again.

One piece of advice, do not fill your containers up to the top...leave some room for expansion.

I had some stored leftover royal icing(it was black) and I came to find quite the mess. It seems the icing(it tends to separate when stored) blew the lid right off. I probably had it filled pretty much to the top.

It kind of reminded me of lava from a volcano.

Cookiemookie, thanks for the advice!! I have a container of black RI filled to the top that is about to have three tablespoons removed from it!

Thanks TexasSugar & cookiemookie. And wow, I didn't know it expands, I'll definitely keep that in mind!

How about putting it in a ziplock bag first then in the plastic container.

If you have time to do a search on here and look through my posts, I do have pictures!
