Unprepared or prepared crust?

Well, it is a bit confusing. I read "unbaked" and "prepared" as meaning the same thing, to wit, a crust that's already been rolled out and put into the pie pan. It does not say to blind bake, so I wouldn't do that.

Also, I looked at the recipe author's blog post for this recipe, which provides no additional insights - other than to suggest that you buy a frozen crust for this pie. (I'd thaw it before filling and baking.) ;o)
