Oregon Hazelnut Shortbread Cookies

Grind roasted hazelnuts in a food processor to a coarse grind. Add
butter and sugar and process thoroughly. Place nuts, butter and sugar
mixture in mixing bowl, and add flour (1/2 cup at a time) mixing each
addition completely. Combine mixture into a ball. Make 1-1/2-inch
balls and place on a non-stick cookie sheet, about 1/2-inch apart.
Bake at 350 for 10-12 minutes. Refrigerate remainder of the dough
until ready to bake.
