I see the folks who win gingerbread house contests say that they have been working on the house for months - but it doesn't fall apart - they can even drive them hours at that age. I can't keep one more than 3 weeks before the royal icing is SOOOO dry that the pieces just start falling off. Does anyone know what tricks these professionals use to keep the house together longer? Would adding glycerin to the RI help - I've been using the antonio74 RI recipe. I don't want to coat it in inedible polyurethane - I don't want to keep it for years, plus I doubt that would really help hold it together. I'd just like it to last 6-8 weeks instead of 2-3 weeks before it starts falling apart.
