In the middle of the day's cooking, thought I'd give these a try.  Can't find 'em ANYPLACE out here:

Can't find Calaveras de azúcar.para el Día de los Muertos (November 1)? (Sugar Skulls for the Day Of The Dead) Make 'em! Here's a simple at-home recipe: 

 Beat egg whites into soft peaks, mix with granulated sugar until the consistency of soft sand (add a bit of water if too dry). Form into little skulls by hand; use kitchen utensils to form eyes, nose and teeth. Let dry 24 hours. Decorate with food coloring or frosting. They're a great holiday activity with the kids. Sugar skulls are ornamental, and not meant for consumption. 

These are my first try; only these four survived a dozen attempted.  Do NOT try to cook these; they just fry and stick to the plate!  Be patient and dry them. 

Forming them:  make a ball of sugar in your hand, and then turn it over.  You'll be amazed how little tweaking it takes to make a little bony head.
