Equipment
Method
- Heat the oven to 325°F and line two baking sheets.
- Cream butter and powdered sugar until smooth, then blend in vanilla.
- Stir in flour and salt just until a soft dough forms. Work in chopped pistachios, lime zest without overmixing.
- Shape into a 2-inch-thick log, wrap and chill 30 minutes; cut into 24 slices and place 1 inch apart.
- Bake 15–18 minutes until bottoms are lightly golden; cool 10 minutes on the tray.
Notes
- Do not overwork shortbread dough; the butter supplies its tender texture.
