they were surprisingly easy to prepare. they are made with egg whites and ultra fine professional grade pure cane sugar. with only those two ingredients, the mixture is whipped over boiling water for five minutes. after the mixture is heated and the sugar is melted, the bowl is transferred to a stand mixture and whipped for another eight minutes on high.
then, the mixture is placed into a pastry bag with a plain round tip, and piped onto sheet pans which are lined with silpat mats. the pans are placed into a preheated 200 degree oven and baked for one hour. since this recipe makes three sheet pans of cookies, i had to bake two of the pans first, and then the last sheet pan separately.
the bones are easy to form with the pastry bag. i simply made two dots, then added the straight line, and finished the bone design with two more large dots at the opposite end.
i chose to serve the cookies on a shiny platter.
