We prepped and assembled about 10 dozen in four hours, not counting steaming time. (They need to steam for a couple of hours after assembly.) So I've got plenty for Christmas, AND a couple of bags for the freezer. Easy dinners, hurrah!
By the way, Andrea says she distinctly remembers that our first tamale day was in my not-yet-remodeled kitchen. Since the remodeling was done in the summer of 1993, that means this is at least our 15th year doing them. I'd say that definitely qualifies as a tradition!
