Maria's Ischli Cookies

Recipe Instructions If you cannot buy nuts already ground, then grind them in a food processor, taking care not to overprocess them or they will turn oily; you can also process them with the sugar to prevent them from turning oily. (Note if you are working with whole hazelnuts, toast them first in a 400 degree oven, rub off skins, let cool and then grind.) Combine the nuts with the butter, sugar and flour; you will have to combine this dough with your hands; if a bit too dry, add drops of lemon juice or rum. Form dough into a roll 1 1 /4-inch thick. Refrigerate overnight in waxed paper or parchment. Following day preheat the oven to 350 degrees. cut dough into 1/4-inch slices and bake on an ungreased cookie sheet for 15 minutes or until golden. Remove from oven and cool cookies on a rack. When cooled to room temperature, sandwich two cookies together with raspberry jam and spread some of the chocolate icing over the top cookie. For a pretty presentation, set them in fluted paper cups. For the Chocolate Icing: Melt chocolate with water and sugar. When melted, add instant coffee and cook over very low heat for 5 minutes. Turn heat off, add butter and let icing cool to room temperature. (Don't let it get too firm or it will be hard to spread over cookies.) This recipe yields 2 dozen.
