varnishing a gingerbread house to preserve it ?
Hi I need to make a gingerbread house early. It's not going to be eaten only for display purposes and I want to stop it going bendy? Please can someone advise if I should varnish it a) what should I use and b) do I varnish it first then decorate with icing after. I'm worried if I varnish first the icing wont stick and if I varnish after it will turn the icing yellow or knock it off?
