Add flour and beat until almost incorporated. Then add chopped cranberries and pistachios and beat until mixed in. The mixture will be sandy. If it does not hold together for shaping, add one tablespoon of softened butter and mix until cohesive.

Divide and form the dough into two logs. Shape each log as round as possible and roll in sanding sugar. Wrap logs in plastic wrap and transfer to the refrigerator. Chill for at least 1 hour or up to several days. Logs should be firm but sliceable.

Preheat oven to 325°F (160°C) and position racks in the upper and lower thirds of the oven. Remove plastic wrap from dough logs. If needed, trim the ends to create straight slices. Slice each log into 12 pieces and arrange on an ungreased cookie sheet, spacing them about 1 1/2 inches apart.

Bake for a total of 18 minutes, rotating the cookie sheets after 9 minutes. Cookies should be firm with undersides just barely golden. Let cookies cool on the baking sheet for 2 minutes, then transfer to wire racks to cool completely.
