Hello, all! I have only been decorating sugar cookies for a short while (like 4 months) so I have only dealt with cold and dry weather. Right before Valentine's Day I was icing a batch of cookies when suddenly it was warm and humid outside! My cookies didn't dry for DAYS! I ended up (after the second day of the royal icing not drying) scrapping the batch and starting over, which by then the weather had changed back to blizzardy winter. I have two orders due soon and the weather is supposed to be warm and wet! How do you lovely cookiers ensure your royal icing will dry out no matter what weather? I usually place in the oven, with it off and door slightly cracked, for safe drying away from tiny fingers/pets, but obviously not changes in humidity. Also, I'd like to note that I work with vegan royal icing which is made with Aquafaba, powdered sugar, vanilla and then I use Americolor food coloring (not vegan) to color.
I'm not sure if anyone will be able to help but even just an idea of how to dry cookies all year-round would be appreciated. Thanks everyone!
