All-purpose flour provides the structural gluten network required to hold heavy mix-ins without collapsing during the double-bake process. Swapping this flour for a lower-protein pastry flour will yield a crumbly texture that shatters when sliced, while high-protein bread flour produces a tough, chewy interior that resists the drying phase. Measure flour by weight or spoon it into the measuring cup to avoid packing excess density into the dough.
Folding shelled unsalted pistachios and finely chopped candied orange peel into the wet-dry mixture requires a gentle hand to prevent gluten overdevelopment. Incorporate these solid additions only after the dough just comes together, ensuring even distribution without toughening the final crumb. Wet or floured hands prevent the sticky dough mass from adhering to your skin during shaping.
Baking the initial formed logs at 350 degrees Fahrenheit for 20 to 25 minutes sets the exterior structure before slicing. Allow the baked logs to cool for precisely ten minutes so the interior moisture redistributes safely. Use a serrated knife for slicing the cooled logs into half-inch portions; a smooth blade will fracture the nuts unevenly and shatter the crisp edges.
Returning the individual slices cut-side down for an additional five to seven minutes drives out remaining moisture to achieve maximum crispness. Storing cooled biscotti in an airtight container preserves their brittle snap for weeks. Stale pieces regain part of their original texture when flashed in a warm oven for three minutes.
