In a large mixing bowl, crumble the almond paste and gradually add 1 cup sugar. Add the egg whites to the almond/sugar mixture and beat on high until smooth. (Dough will be stiff.) Insert large star tube in pastry bag; fill with dough. Using a slight, swirling motion, squeeze dough on well-greased cookie sheet; lift tube 1/4 inch from pan until dough breaks easily. Or, drop dough from teaspoon on well greased cookie sheet. Bake at 350 degrees for 15-18 minutes. Immediately remove from pan. Cool on rack. Makes about 3 dozen.
