"I followed the recipe exactly and the cranberry glaze didn't set up at all. Making it a second time I used two more packets of gelatin for the glaze and it worked much better. Adding food coloring to the panna cotta for a gray color made it much more effectively gruesome. The taste was only so-so, however. I think people really would have preferred normal jello flavors to the slightly sweet blandly vanilla flavor this provided; I served this at a party and most only tasted a slight amount from curiosity and didn't come back for seconds. I'll be trying this recipe again for Halloween, but will substitute actual jello for the unflavored gelatin and vanilla.
