Gather dough into ball and divide into five equal pieces. Roll each piece into a cylinder. If you wish, roll each cylinder in colored sugar. Wrap in wax paper and refrigerate overnight.
Preheat oven to 350. Cut each log into 1/4" slices. Bake on ungreased cookie sheet for 8 minutes. "This recipe is a tradition in my husband's Swedish family. It makes enough cookies to feed the Swedish Army."
