As long as your bowl is clean, and you don�t accidentally get any egg yolk in there, you should be fine. It may take a while, especially if you do it by hand, but if you keep whisking, eventually you should get a nice, glossy meringue that will hold a shape when piped.
Speaking of which, you can make this in any shape you want, in case you were thinking about trying to do a full skeleton (show off). Of course, different shapes may change the cooking time, but you�ll figure it out. As long as your meringue feels firm and dry, you�re probably in good shape to let it cool in the oven.
By the way, I did these on a very humid day in San Francisco, and as they sat on the plate, they sort of stuck together a little bit. They came apart fairly easily, but I wanted to ask our experienced bakers and candy makers if there�s a trick to prevent this kind of thing? Maybe some powdered sugar or cornstarch? Let me know if you have any ideas.
These are probably a little too time-consuming, delicate, and completely inappropriate to use for Halloween trick-or-treaters, but if you�re having a holiday themed party, these would be a hit. I hope you give these meringue bones and ghosts a try soon, and as always, enjoy!
Ingredients for about 2 dozen small bones, or other shapes:
2 large egg whites, room temp (don�t get any yolk in it or it will not work!)
1/8 tsp cream of tartar or fresh lemon juice
a scant 1/2 cup sugar (that means almost, but not quite full), added a spoon at a time, once the egg whites start forming a very soft meringue
* bake at 225 F. for 1 hour, then turn off oven and let cool with door closed another hour
