1 cup of all-purpose flour
1/2 cup of powdered sugar plus more for pressing cookies
1/2 cup (1 stick) chilled unsalted butter, cut into 1/2 inch cubes.
2 Tbsp of sliced fresh basil leaves
1 tsp of finely grated lemon zest
1 Tbsp of fresh lemon juice
1/2 tsp of finely grated lime zest
1/4 tsp kosher salt
Sanding Sugar (optional)
Pre heat oven to 375 degrees. Place flour, 1/2 cup of powdered sugar, butter, basil, both zest, lemon juice, and salt in a food processor. Pulse until large, moist clumps form. Measure level tablespoonfuls of dough; roll between your palms to form balls. Place on a large baking sheet spacing 2 inch rounds, dusting cup with powdered sugar and press cookies into 2 inch rounds, dusting cup bottom with powdered sugar as needed to prevent sticking. Sprinkle tops of cookies with standing sugar, if using.
Bake until edges are brown, about 20 minutes. Transfer to a wire wake; let cool.
