I ran out of time this week and am trying to dry fondant fast. Can I use the oven method for drying homemade MMF? Won't the heat melt the marshmallow? I have to make the sides to a wine box cake due Sunday (it is Thurs) and I just made the MMF today. Hoping to roll out and cut the panels tomorrow (Fri). Two days is not nearly enough time to dry MMF I don't think. Debating kneading in some dark brown gumpaste I have to make the light brown fondant look more like wood. Can I swirl gumpaste with fondant like this, so that it has a swirled/grain look versus kneading it in completely?
