For the cleanest slices, rotate the dough log a quarter turn after every couple of cuts and use a gentle sawing motion; if mix-ins cause crumbling, press stray bits back into the sides before baking. Toasting the pistachios lightly enhances flavor and crunch. If the dough feels crumbly before chilling, knead it once or twice in the bowl to bring it together, but avoid overmixing to keep the shortbread tender. You can dip or drizzle cooled cookies with melted white chocolate and sprinkle with extra chopped pistachios for a festive finish. The dough logs freeze well for up to 2 months; slice from frozen and add 1–2 minutes to the bake time.
