Just Sept 21 I assembled 8 apple crostatas, wrapped & put 'em in freezer so then on Sep 23 which
was the day I wanted to serve them, all I had to do was pull them out of the freezer, brush on the egg wash, sprinkle on raw sugar and bake. I baked 2 at a time in my oven so it went really fast, and they were all done and ready to go in no time (well, it was really a little over 4 hours of baking time total!) wigs
PS: I think crostatas taste pretty darned good the day after they've been baked, but IMHO pie crust tastes best baked on THE day I eat it--and this was a catering gig.
