Roll the dough into walnut-size balls and place them 2 inches apart on cookie sheets. Flatten each cookie with a fork that has be dipped in sugar.

Additional Hint; I used Parkay Tub margarine and orange flavored cranberries. It gave the cookies a hint of orange flavor. Cranberries come in different flavors from Ocean Spray so these cookies can take on yummy results.
I also did not chill the dough and used a medium cookie scoop and I did press them with a fork dipped in sugar. These cookies do spread so make sure they are at least 2 inches apart. They were a hit with my family.
