I grew up with mom making these treats only at Christmas. I was the one who got to taste the ones that broke. These are Extremely Fragile. But they are great. I have gotten compliments from people who don't like almonds. When I moved out of moms, I had to BEG her for the recipe. It is from an authentic German cookbook that Mom has had since she was a young woman. She had to translate ingredients and the measurements for me. The almonds need to be blanched and slivered. Prep time doesn't include the time to Blanche and sliver the almonds if you buy them with the skins on. At the end of the directions, is the directions for making vanilla sugar if you do not know how.
