Buttery, melt-in-your-mouth shortbread cookies studded with vibrant pistachios and dipped in rich dark chocolate.
Ensure butter is at room temperature for a smooth dough.
Do not overmix the dough once flour is added to keep cookies tender.
Chilling the dough thoroughly is crucial for maintaining cookie shape.
Keep an eye on the oven; cookies are done when edges are just golden.
Let cookies cool on the baking sheet for 10 minutes before moving.
