There are similar versions to this cookie, but I truly think that if you make mine like directed, you will find that these are the best. They will melt in your mouth. This has been a recipe used in my family since I was a little girl. We always made them for Christmas and weddings, but they are good anytime. The key is to use butter and make sure you grind the nuts very fine. I use my Kitchen Aid grinder attachment, but you can also use a food processor. Other versions use just chopped nuts, but I think when they are finely ground that makes the difference. Another important step is to bake them at 250 degrees for 45 minutes. Again, the other versions don't do this, but I stick with my recipe and am never disappointed. The extra time is worth it! This recipe will probably make 100 balls, depending on how large you make the cookies. The baking time listed is just an estimate. It will vary depending on how many cookies you make and how many you put on a cookie sheet. You can fit quite a bit on a cookie sheet because they really don't spread much.
