Yeah, I don't like the edible lacquers for the same reason. I find that dehydrating cookies always leaves them with a subtle satin finish. (Removing moisture from the drying environment will always do this, whether you use a dehydrator, heat fan, or some other method of quick-drying.) You can also paint cookies with corn syrup to give them a super shiny finish, but watch out: depending on your conditions (humid or not), the corn syrup may never completely dry, or may dry and then get tacky again if exposed to humidity. The latter is OK if you're not packaging your cookies, but can get problematic if you are. Yankee Girl Yummies did a whole post on the corn syrup technique for this site a few months ago; a good read: http://cookieconnection.juliau...-syrup-a-woeful-tale
