Chilling is crucial for clean spirals, so don’t skimp on the firming time before slicing; if the dough softens, pop it back in the fridge for 10 to 15 minutes. For tidy edges, trim the first 1/2 inch of each log before slicing. If your filling feels too loose, beat in 1 to 2 tablespoons more confectioners’ sugar; if too stiff, add a teaspoon of cream at a time. Use high-quality, unsalted, fresh pistachios for best color and flavor, and avoid over-processing them into paste. To help prevent cracking, gently compress the log after rolling to remove air gaps. You can swap almond extract for vanilla in the filling for a milder flavor, and add citrus zest to the dough for a bright twist.
