It's really hot in Dallas today and I need to leave my dried Royal Icing Flowers in the car from 10:30A - 3:00P. They are in egg cartons. Do I need to put them in an insulated bag or are they ok in a regular tote bag?
They'll be just fine, neighbor. Heat doesn't really bother royal icing. Sometimes I use a desk lamp or a low oven to help my royal icing dry faster.
