For clean slices, let the dough chill thoroughly and use a thin, sharp knife, wiping the blade between cuts; if the dough crumbles, let it sit at room temperature for 5 minutes before slicing. Weighing the flour (240 g) helps prevent a dry, crumbly dough, and if needed you can add 1 to 2 teaspoons of milk to bring the dough together. Toasting pistachios lightly before chopping enhances flavor, and you can roll the dough logs in coarse sugar or finely chopped pistachios before chilling for a decorative edge. Swap in orange zest (1 teaspoon) or almond extract (1/4 teaspoon) for a flavor twist, and store baked cookies in an airtight container for up to 1 week or freeze the dough logs up to 2 months.
