I like to make a pan of these, cut the whole thing in two pieces, slip a cardboard
under each slab for support, then wrap each slab in several layers of plastic wrap. Fits well for mailing in the flat-rate boxes.
Makes a great present when you can't attend a function, but still want to "be there" as part of the fun. Since individual pieces aren't cut yet, the slabs stay fresher longer, in my opinion.
