SC - molds for gingerbread

[Bethany Public Library]

Hallo! I am suddenly stuck with an idea, and wonder if anyone has tried
anything like it for a soteltie.

I need a mold to bake gingerbread in (the hard cookie renaissance Italian
sort, not the cake or early period sort w/breadcrumbs), so as to make a
vessel, and wonder if anyone has baked gingerbread in a carved plaster mold
before.  I've never used plaster in the oven before, but if I line it with
foil or grease the plaster, it might work. I think I could get a very high
level of detail in that manner.

Thoughts, anyone?

Cheers

Aoife
