Buttery, melt-in-your-mouth shortbread cookies packed with toasted pistachios and brightened with a zesty lemon hint, topped with a vibrant raspberry glaze.
Always use room temperature butter for smooth dough and tender cookies.
Chilling the dough is essential for preventing spread and maintaining cookie shape.
Toast your pistachios for a deeper, nuttier flavor that really shines through.
Don’t overmix the dough once the flour is added; mix just until combined.
For a perfectly smooth glaze, ensure you press the raspberry puree through a fine-mesh sieve.
